I’ll be conducting a daily live blog Friday-to-Monday during the combine workouts. I hope you’ll join in the debate and get involved. Today I wanted to run through some of the things I’ll be looking out for over this year. Measurements begin on Wednesday with the OL’s, TE’s and PK’s. Workouts begin on Friday. For a full schedule breakdown, click here.

— Eli Harold is a perfect LEO pass rusher. He’s long, lean and explosive. I think he could end up going in the top ten. Is there a more natural fit for Dan Quinn if he wants to emulate Seattle’s scheme in Atlanta? Cliff Avril and Bruce Irvin are good comparisons for what to look for. Avril ran a 4.51 with a 1.50 ten yard split. Irvin ran a 4.50 with a 1.55 ten yard split. They were both 6-3 — Avril had 8lbs on Irvin (253 vs 245). Harold is listed at 6-4, 250lbs.

— Will LSU defensive end Danielle Hunter win the combine? He has a ridiculously low body fat percentage (4%), he’s incredibly long and fluid. Personally I think his tape is horrendous but you can see the upside based purely on athleticism. He could go off in Indianapolis, excelling across the board in every drill.

— Who are the candidates to challenge Hunter? Eli Harold has to be in with a shout. Owamagbe Odighizuwa is built like a Greek God and could have a Ziggy Ansah type weekend. Ansah ran a 4.63 at 271lbs, had a terrific 4.26 short shuttle and a 34.5 inch vert. Odighizuwa doesn’t have Ansah’s 35-inch arms but he has enormous 11-inch hands and similar size (266lbs).

— Melvin Gordon is a workout machine. A true gym rat. Let’s see if all the work was worth it here. Jamaal Charles, the player he’s often compared to, ran a 4.38. I wouldn’t expect that kind of speed, but he’s probably a solid 4.4 runner. He has a fantastic, errr, ‘ass’, so he could challenge the 11-2 broad jumps by Lache Seastrunk, Anthony Alridge and Carl Stewart (best recorded jump in last ten years).

— Can William & Mary receiver Tre McBride prove he’s a fantastic athlete? Reports suggest he can get into the 4.4’s. I need to see it to believe it. Even if he runs in the 4.5’s — it shouldn’t be a concern. He’s shown enough suddenness, playmaking ability, ball skills, size and character to warrant serious consideration possibly as early as the late second round. He’s one of the most exciting receivers in the class and deserves more attention.

— Will Tevin Coleman work out? Tony Pauline reported in December he was carrying a foot injury. He was compared to Darren McFadden by Mike Mayock today. It’d be interesting to see if he can get anywhere near McFadden’s 4.33 forty time. UPDATE — Gil Brandt has confirmed Coleman will not participate.

— How fast is Jaelen Strong and what is his broad jump? I think he’s going to produce an excellent vertical with his basketball bloodlines. The main concern is separation skills. Can he show initial quickness in the forty and lower body explosion in the broad? He’s got a real chip on his shoulder — his Twitter timeline is a constant stream of retweeted criticisms. Let’s see if he can prove the doubters wrong.

— Just how fast are Devin Smith and Phillip Dorsett? I think Dorsett has a clear edge between the two and should provide the fastest time over the four days. Considering both players lack size, speed is going to be crucial. The quickest time by a receiver in the last ten years was the 4.27 by Marquise Goodwin in 2013, followed by Jacoby Ford (4.28) and Darrius Heyward-Bey (4.30). If I had to guess, I think Dorsett runs in the 4.3’s.

— Sammie Coates and Breshad Perriman have similar traits. They look the part and should have excellent combines. They need to. They have to convince teams to invest in upside potential because catching the ball consistently is a problem for both. If they want to generate high second round (or even first round) grades, they have to live up to expectations and test well across the board. And they need a team or two to believe they can improve with a summer on the jugs machine. Athleticism alone wasn’t enough for Cody Latimer (who had amazing hands) to get in round one. I think Coates and Perriman will struggle to crack day one, but if they’re going to — it’ll be down to their physical skills.

— Can Dorial Green-Beckham make a statement? He doesn’t just have to ace team interviews in Indianapolis. I think he needs to speak well to the media and show a ‘changed man’ vibe. I want to see him answer some difficult questions. On the field he needs to flash freak-of-nature talent at 6-6 and 225lbs. This is an opportunity to regain some momentum. The character concerns are legit and damaging for DGB. He needs to make some positive headines. Cornerback Marcus Peters faces a similar test — although I expect he’ll ace team and media interviews. He’s a smooth operator.

— How quick is Nelson Agholor? Watching him dunk a basketball, compete all over the field, return punts and play with real grit and determination makes you want to believe in the guy. A really good forty time could pump up his stock. Running a 4.52 last year hurt former teammate Marqise Lee. I’m not sure he has the potential to add too much weight and he’s skinny. That’s a concern. Guys without size need to be sudden and quick. I think he can beat Lee’s time. I like him.

— Just how special is Devin Funchess? Speaking of dunks, how about the video posted in yesterday’s piece? Expect an incredible vertical jump. I think he can produce a terrific 3-cone too, he shows good change of direction skills on the field. The main concern is he’s a build-up-speed runner and might not break the 4.7’s. If he can crack the 4.6’s — watch out. He’s working with the TE’s not the WR’s. Mike Mayock says he has better movement skills than Kelvin Benjamin. Funchess is the biggest enigma in the draft.

— Will we see any separation among the top three receivers? Hand size, forty times, vertical jumps — all could be difference makers for Amari Cooper, Kevin White and Devante Parker. For me Cooper is the cream of the crop and could surprise a few people. He’s more athletic than he gets credit for.

— Yesterday we discussed how Maxx Williams won’t be judged on speed. He has a knack of making plays, he has exceptional character and he’s just a good football player. But if he can impress here with a great work out — and if he has above average length/hand size, it won’t hurt. If Coby Fleener can manage 27 reps on the bench press I’d like to see that from Williams. He doesn’t look particularly toned in the arms. Has he got natural strength? If he is going to run in the 4.8’s like Marcedes Lewis — a 37-inch vert would be a nice trade-off.

— How does Penn State tight end Jesse James perform at 6-7 and 245lbs? We’re all looking for a freak of nature TE. At that size it’s harsh to expect a remarkable workout. You can guarantee if we do see a special workout warrior at TE this year (we didn’t in 2014) he’ll be going earlier than he probably should. Every team is looking for the next Gronk/Graham. Of all the tight ends capable of making a statement — Wes Saxton at South Alabama might be the guy. He’s lighter (6-4, 235lbs) and that could help in the quickness drills. He looks good on the field.

— Which of the OT’s separate? Every year athletic linemen really boost their stock. It’s why Eric Fisher ultimately usurped Luke Joeckel as the #1 pick in 2013. It’s why Lane Johnson propelled himself into the top-five. D.J. Humphries at Florida has reportedly added 20lbs of weight. He’s long and smooth. If he can show mobility despite the extra size he could jump into the round one mix. T.J. Clemmings should also impress physically. Teams really focus on the athletic qualities here — much more so than they used to. Greg Robinson, Taylor Lewan and Joel Bitonio were all incredible athletes with consistently good physical traits and drill performances. It’s no surprise Lewan and Bitonio impressed in year one. With the best athletes in college playing on the D-line these days, agility on the O-line has become absolutely vital.

— Will Andrus Peat and Ereck Flowers perform as well in the kick-slide drill as I expect? Can they match it with the length and strength to cement their place in round one? Can Brandon Scherff and La’ell Collins convince teams they can play tackle? How will Ty Sambrailo do in the bench press? He needs to show strength to match his foot speed. Can Jake Fisher likewise show upper body power and maybe a little extra (good) weight? How athletic is Penn State’s Donovan Smith or Corey Robinson at South Carolina?

— Is Leonard Williams as good as advertised? I think he shows real flashes of quality and his production at USC is good. But I’m not sure he’s quite the player he’s been hyped up to be in the media. If he shows up here with a supreme workout — I’ll eat my words. Speaking of USC prospects — how does running back Buck Allen perform? He doesn’t flash eye-catching size, speed or power — but he cuts on a dime. He has a shot to break round two as a top-notch cut-and-run back.

— How big is Shane Ray? He’s listed by Missouri at 6-3 and 245lbs but he looks smaller on tape. If he’s 6-1 and lacks length, how does that impact his stock? Rest assured he’ll do well in every drill as an explosive pass rusher. But teams value length and size, especially if you’re going to play D-end in the 4-3.

— I’ve seen some tape complaints on Oklahoma nose tackle Jordan Phillips. You know who had lousy college tape? Dontari Poe. Then he ran a 4.98 and went in the top-12 picks in 2012. If Phillips can run a similar time — and if he passes all the medical checks on his back — don’t be shocked if he enjoys a similar rise.

— Arik Armstead appears to be a favorite within the various front offices, much more so than in the media during the 2014 college season. He’s listed at 6-8 and 290lbs. Let’s see how big he really is and whether he can put on a show at that kind of size. You want to believe he’s another Calais Campbell. And yet Campbell didn’t have an amazing combine — running a 5.04 in 2008, posting 16 reps on the bench press (long arms — problematic here) and a 29.5-inch vertical. He had a 1.69 ten-yard split. It’ll be interesting to compare.

— We’ve been waiting 18 months to see Vic Beasley run a forty yard dash. He’s small, light and lacks length. It’s all about the speed with Beasley. Can he get anywhere near Bruce Irvin’s numbers (size and speed)? He’s going to have to run in the 4.5’s at least — you’d hope for the 4.4’s if he’s in the 230-240lbs range. He needs a great ten yard split too. Given his shorter arms you’d like to see a not-hopeless performance on the bench press too to alleviate some of the strength concerns. Irvin had 23 reps.

— I don’t see any of Carl Davis, Preston Smith, Henry Anderson or Mario Edwards Jr going in the first round. But they get hyped up a lot, so let’s see how athletic they really are. Smith is the most intriguing with excellent size and length. I’m just not sure he’s a top-athlete. Datone Jones forced his way into round one with a 4.80 forty, 112-inch broad jump and an excellent 4.32 short shuttle. That’s the benchmark for guys like Smith and Edwards Jr. Davis is bigger and has to look good compared to Malcom Brown and Eddie Goldman — two former 5-star recruits. As well as he played at the Senior Bowl, Davis’ tape is rank average.

— The defensive tackle I’m most interested in watching here? Washington State’s Xavier Cooper. I watched my first batch of games last week and he was very, very impressive. A possible second or third rounder for me, but I want to watch more before making a firm judgement.

— Hau’oli Kikaha’s medical checks will be interesting. Is he 100% healthy? And how athletic (or not) is he? He has the production, he’s a great hands fighter and he just gets to the quarterback. But he’s going to need to prove he’s more than a good college player. I’m not overly optimistic. If he he’s healthy though, teams will take interest in his production.

— Alabama safety Landon Collins was touted as a SPARQ demon a couple of years ago. Here’s your chance to prove it, Landon. In an especially weak year for safety’s he could go very early.

— LSU cornerback Jalen Collins is one of my favorite players this year. I think he could be a top-15 pick. He has the size and length. We know that already. I think on tape he shows rare athletic qualities too (eg chasing down Melvin Gordon in the open field). Monday could be his day. Get ready because Collins is a stud in the making. Jonathan Joseph ran a 4.31 at 5-11 and 188lbs in 2006. I’ll stick my neck out and say Collins pushes the 4.3’s at 6-2 and 198lbs.

— In terms of later round corners, I really like Alex Carter, Steven Nelson and Damian Swann. Out of the three, I suspect only Swann ticks the required ‘length/size’ boxes for Seattle. Which other corners stand out athletically to be the next possible Sherman/Maxwell/Browner? It’ll be a fascinating watch on Monday. This is the position, more than any other, where you can look at a sheet of measurements and eliminate three quarters of the group and focus on certain size ideals.

— Is Quinten Rollins a safety or a corner? You can ask the same question about Utah’s Eric Rowe. They need to show nimble footwork, change of direction skills, initial quickness and explosion. Still, Richard Sherman didn’t have the greatest combine so it’s never worth ruling anything out.
