These rankings were compiled using a weighted formula based on my top-500 pre-draft rankings, with quality outweighing depth of class. Here's my list of the top available UDFAs in this year's class from top to bottom, not broken up by teams.

Note: Some teams were far less aggressive in this year's UDFA sweepstakes due to AAF signings (the Panthers being the biggest example). AAF signings were not factored into these rankings.

1. New Orleans Saints

Huge haul, here: Ozigbo, Granderson and Hansen are all guys who are easy to picture contributing in the NFL. Each should have been drafted.

2. Miami Dolphins

Nobody would have batted an eye if Calhoun, Williams and Hanks had been taken anytime from mid-Round 5 on. Any of the three could provide the Fins value down the road.

3. Kansas City Chiefs

Fields got pushed out of the draft because he's slow and small, but the kid can play. Has NFL slot ability. James Williams was such a perfect fit for a pass-happy Air Raid-lite pro team like the Chiefs -- superb receiving back for Mike Leach at Wazzu.

4. Seattle Seahawks

The Seahawks scored points for bringing in Thomas -- a guy who absolutely should have been drafted on his insane measurables alone -- and for accruing depth. If there were ever a UDFA corner literally built for Seattle, it's Thomas. He's got the length, he's got the athleticism -- they're just going to have to teach him the rest of it.

5. Oakland Raiders

Roemer fell out of the draft because of off-field concerns, Coney did because of athletic testing, Doss reportedly did because of an injury, and Ingold did because of the position he plays -- but each has the skill to hang long-term in the NFL.

6. Chicago Bears

Hall reportedly fell out of the draft because of personality issues, but he's a world-class athlete you bring in to see if he can keep his head screwed on straight. Bars is an awesome flier -- if he hadn't gotten hurt last year, he may have been drafted in the middle rounds.

7. New York Giants

Really like the offensive line signings. And White and Dungey were both back-of-the-draft guys that I thought were worth developing on practice squads.

8. Philadelphia Eagles

The Eagles swooped up three draftable guards -- I predict they'll find at least one in the group who'll hang (and they may get two). Edwards was worth a shot on college play alone. Note: The Eagles signed and then in short-order waived Temple S Dalvon Randall, who previously appeared on this list. So much for brotherly love!

9. Dallas Cowboys

My favorite flier here is my beloved Kansas Jayhawk Daniel Wise. Super underrated player who got ganged up on in college because his supporting cast stunk. Wise's father played in the NFL, and his brother currently does. Interesting 3-tech prospect if he can add a little weight.

10. Tampa Bay Bucs

How in the heck did Anthony Johnson go undrafted? The NFL didn't consider the full extent of the circumstances he played under last year, in my opinion. I thought he and Michael Gallup were close to analogs in 2017. If Johnson gets back to that level, he's gonna hang for awhile. For me, he's a mid-round pick for the price of free.

11. Baltimore Ravens

Willis finally broke out last year and was No. 118 on PFF's draft board. He fell out of the draft because of off-field concerns and the one-year wonder thing.

12. Houston Texans

Huggins would have been drafted if Christian Wilkins had declared for the draft after the 2017 season, as expected. Higdon is on the five-player short-list for the "Phillip Lindsay of the 2019 class." Also loved the fliers on Lewis and Davis, two athletic players who flashed havoc-wreaking chops in college. Gonna miss Davis in MACtion. Goodbye sweet prince.

13. Jacksonville Jaguars

Giles-Harris was a killer in the ACC who fell out of the draft after getting injured and then testing poorly. Saivion Smith made a mistake in declaring.

14. Tennessee Titans

After testing like he did, it was quite surprising to see Barnes fall out of the draft. He's a better player than Bo Scarbrough, and he can do almost everything that Ballage can do.

15. Denver Broncos

Wouldn't surprise me at all if Rypien had a longer career than second-round pick Drew Lock. I wish a book would offer me juicy odds on Rypien starting more career games. Shoutout to my Jayhawk brother Joe Dineen, who was an absolute tackle machine behind Daniel Wise on the otherwise dreary KU defense with 220 over the past two years.

16. New England Patriots

The Pats smoked the draft and didn't have to do much in the UDFA portion of last weekend's show. Gant and Meyers could stick, and Beck has sleeper appeal on this team because of his diversified H-back skillset.

17. Detroit Lions

Per reports, Benzschawel had contract offers from half the league or more -- the Vikings were among teams burning up his phone line when the draft concluded on Saturday night. I was lower on Benzschawel than some, but I still found it odd he didn't get drafted.

18. New York Jets

Dortch was one of my favorite players in college football. I'm telling you: The kid is going to hang. I don't care about the measurables. He can play.

19. Cincinnati Bengals

A week removed from the draft, and I still can't figure out how Stanley Morgan went undrafted. If you want my leading candidate for this year's UDFA skill guy that ends up starting more than 30 games in the NFL, he's the guy. Should be a really good NFL backup, if nothing else.

20. Los Angeles Rams

I thought Hitner's showing in athletic tests might get him drafted. He offers future swing versatility if he makes the practice squad and develops any. Keenen Brown is a guy Sean McVay can potentially find use for, and Boogie Roberts was a bit underrated because of the way San Jose State (mis)used him as a 0-tech nose tackle. I see a Quad-A three-tech tweener.

21. Indianapolis Colts

Penny Hart!!! No college football fan will be surprised if he catches 60 balls from Andrew Luck in 2020. I'm just telling you.

22. Green Bay Packers

Outside of Stanley Morgan, Nijman was my other "why in the (expletive) didn't this prospect get drafted?!" guy. On measurables alone, he's worth a fifth- or sixth-round flier. 6'7/324 tackles that move like that don't grow on trees, ya know.

23. Atlanta Falcons

I'm almost as bullish on Zaccheaus as I am Dortch. You have to look past the measurables on guys like that. Zaccheaus can contribute in so many different ways.

24. Cleveland Browns

I thought Ray might hear his name called. Overshadowed by Harold Landry and Zach Allen in college, he's worth a look in camp.

25. Arizona Cardinals

Nice choice by Sweet here, as Arizona only tossed a couple late Day 3 darts at their problematic offensive line last weekend.

26. Buffalo Bills

Top-heavy class headlined by Josh Allen's dueling Spiderman GIF Tyree Jackson and the uber-productive David Sills, a former quarterback turned star West Virginia receiver.

27. Washington Redskins

Chidi Chidi Bushell-Beatty.

28. Pittsburgh Steelers

Rk Player Pos Ht Wt Comp SPQ RAS 243 Fred Johnson OG19 6'7 326 John Wetzel 11.2 3.49 406 Chris Nelson DL38 6'1 298 Malcom Brown 10.3 1.51 427 Garrett Brumfield OC17 6'3 289 Ted Larsen 66.5 8.04 446 Travon McMillian RB38 5'11 210 Jonathan Franklin 18.2 5.8

There are guys out there who think Johnson can stick as a backup swing lineman.

29. Los Angeles Chargers

The Chargers killed the draft but mostly slept through its aftermath.

30. Minnesota Vikings

The Vikings hilariously gave Jake Browning the highest UDFA signing bonus in NFL history after taking a long-snapper late in Round 7 (Twin Cities reporter Darren Wolfson postulated after the draft that that suspicious one-two step was likely a favor to Browning's agent -- Browning signed for more as a UDFA than he would have gotten had he been picked in the back-half of the seventh round).

I think Keenoy (a MAC standout and prolific #grinder who is moving to the same town as his former coach, now-Minnesota HC PJ Fleck) and Blasingame (who flashed in analytics models to do his receiving rate stats and size/athleticism combination) are probably better players. (Even though Browning is the heavy favorite of the three to stick around the longest because of his contract).

Myself and popular Minneapolis podcaster Andy Carlson have started a "turn Blasingame into Larry Centers" movement around town. Blasingame is only two inches shorter and 10 pounds lighter than second-round "TE" Irv Smith. And Vikings fans, here's a sobering thought: Blasingame tested better than Smith in literally every single metric, the forty (4.55 to 4.63), the 20-yard split (2.61 to 2.74), the 10-yard split (1.52 to 1.68), the short shuttle (4.18 to 4.33), the 3-cone (6.94 to 7.32), the bench (20 to 19), the vertical jump (38.5 to 32.5) and the broad jump (10.92 to 9.17). Fun!

31. San Francisco 49ers

Al-Shaair considered declaring in the previous class after collecting 258 tackles between 2016-2017. Most unfortunately, he suffered a devastating ACL/MCL knee injury in 2018.

32. Carolina Panthers

Rk Player Pos Ht Wt Comp SPQ RAS 256 Elijah Holyfield RB20 5'10 217 Matt Asiata 2.8 2.56

The Panthers mostly sat on their hands during the UDFA process because of all the AAF guys they signed. Holyfield could turn into a short-yardage banger. It would be fun to see him hang up the cleats and try to cut to 185 to become a UFC middleweight. We need a Holyfield back in the fight game more than Carolina needs a practice squad scrapper.
