1. Any of the quarterbacks

This isn’t unique to this year’s class. Quite simply, the NFL has had a whale of a problem evaluating quarterbacks from college offenses in recent years. Below is the list of quarterbacks drafted in the first round since Andrew Luck went No. 1 overall to the Colts in 2012:

• Robert Griffin III (2012 by Redskins)

• Ryan Tannehill (2012 by Dolphins)

• Brandon Weeden (2012 by Browns)

• E.J. Manuel (2013 by Bills)

• Blake Bortles (2014 by Jaguars)

• Johnny Manziel (2014 by Browns)

• Teddy Bridgewater (2014 by Vikings)

• Jameis Winston (2015 by Buccaneers)

• Marcus Mariota (2015 by Titans)

• Jared Goff (2016 by Rams)

• Carson Wentz (2016 by Eagles)

• Paxton Lynch (2016 by Broncos)

That hit rate is atrocious. When quarterback-needy teams such as the Browns, 49ers, and Jets pass over the position altogether, that’s pretty telling for this year’s league-wide evaluations.

2. Jabrill Peppers, DB, Browns (Round 1, No. 25 overall)

Go back to the 247 Sports profile of former Michigan DB Jabrill Peppers when he was coming out of Paramus Catholic in 2014, and it lists his position as “athlete.” Three years later, not much has changed. Peppers can take handoffs, return kicks, play linebacker, box safety, slot corner, or deep safety, yet he’s never shown the ability to be dominant at anything except returning kicks. For a guy who’s supposed to be a playmaker, it’s a little discouraging that he got his hands on one pass in all of 2016. At the end of the day, Peppers may just be a safety, and that’s a role we’ve never quite seen him play full time.

3. Adoree’ Jackson, CB, Titans (Round 1, No. 18 overall)

Former USC CB Adoree’ Jackson is extremely similar to Peppers in that the Titans are banking on a prolific athlete to improve by leaps and bounds once he gets the chance to focus on one position. One needs look no further than the Utah game this past season (121 yards and one touchdown surrendered; 117.8 QB rating into his coverage) or the Notre Dame game in 2015 (132 yards and one touchdown surrendered; 158.3 QB rating into his coverage) to realize that Jackson was far from a shutdown corner in college. Even with track speed, Jackson still had the unfortunate habit of getting beat deep, yielding catches of 70, 56, 40, 30 and 29 yards just this past season. There are reasons to be encouraged, though, as Jackson spent his springs running track at USC, and now gets to focus on football full-time. He could certainly reach his full potential and be well worth the selection, but he’s a good ways off that at the moment.

4. Evan Engram, TE, Giants (Round 1, No. 23 overall)

The former Ole Miss tight end is yet another player whose “tweener” status may get mistaken for versatility. For all intents and purposes, Engram was a slot receiver at Ole Miss, with only 229 of his 665 snaps coming as an in-line tight end. The reason: Even in college, Engram was a liability as a run-blocker. At 6-foot-3, 234 pounds, those issues will only get exacerbated at the next level. Last season, Will Tye took 561 of his 731 snaps from an in-line position. The Giants’ heavy reliance on 11-personnel (one back, one tight end and three receivers) basically demands an in-line tight end to have any threat of the run. If New York expects people to fear their rushing attack with Engram lined up on the end of the line, the Giants could be in for a rude awakening. That means Engram is essentially a slot receiver in the NFL, as well, and the Giants already have a pretty good one there in second-year player Sterling Shepard.

5. Garett Bolles, OT, Broncos (Round 1, No. 20 overall)

There are two reasons we at PFF rated former Utah OT Garett Bolles lower than most. The first: Bolles led the nation with 17 penalties a season ago. At a position where attention to detail and consistency is extremely important, that’s a red flag. The second: Bolles allowed 20 total pressures a season ago on 472 pass-blocking snaps. Of all the tackles drafted in the first round of the last three drafts, only Seattle’s Germain Ifedi and Cincinnati’s Cedric Ogbuehi surrendered more during their last season of college. That’s not great company. Bolles has a physicality in the run game that you can’t teach, but tackle is first and foremost a pass-protecting position. Denver’s pass protection was a disaster last year, with the two tackles ranked 51st and 58th in PFF’s pass-blocking efficiency metric (out of 61 eligible players), so the bar is low. With a first-round pick, however, the expectations are high.
