Prospects PFF does not like as much as others include:
DI DAVIYON NIXON, IOWA
PFF Big Board Rank: 66
If you turn on the right game, Nixon looks like a first-round talent. His outing against Northwestern this past season, when he racked up 10 defensive stops and three sacks, is a prime example. But if you turn on his tape against Minnesota, Illinois or Wisconsin (sub-60.0 grade in each), he seems like a sure-fire Day 3 pick.

Nixon finished the 2020 season with a subpar 73.1 PFF grade that failed to crack the top five in the Big Ten. He is quick, explosive and attacks viciously, but the inconsistency in his lone year of starting experience and how often he got stuck on blocks are too big of concerns.
T JALEN MAYFIELD, MICHIGAN
PFF Big Board Rank: 70
Mayfield is likely a tackle-to-guard convert at the next level. He'll be a project for whichever NFL team drafts him, but he is young (20 years old on draft day) and has a physical makeup that presents a lot of upside. That potential makes him a prospect worth taking a chance on during Day 2, but not in the first round.
Mayfield came to Michigan as a four-star recruit, according to 247Sports, back in 2018 and put together up-and-down performances. He was inconsistent throughout his only full season as a starter in 2019, flashing high-end reps but also constantly showing how unrefined he is technically.
In pass protection that year, he gave up 27 pressures en route to a 68.8 pass-blocking grade. As a run blocker, Mayfield flashed his power on several occasions, racking up the second-most big-time blocks among Power Five right tackles — behind only Jedrick Wills Jr. But Mayfield negated that with a negatively graded block rate that ranked in the 13th percentile at the position.
DI LEVI ONWUZURIKE, WASHINGTON
PFF Big Board Rank: 76
Our differences with Onwuzurike lie in his down-to-down consistency when he finally grabbed a starting job in 2019, the fact that we rarely saw him recover if his first move failed and how most of his dominant wins were a result of his explosiveness.
Onwuzurike shined in 2018 with a 90.8 PFF grade, but that was in a limited role while averaging roughly 28 snaps per game. In 2019, he rightfully grabbed a starting spot, increasing his average per-game snap count to approximately 39, but his production took a hit. His PFF grade dropped to 82.5.
When watching Onwuzurike at Washington, it was apparent that he was one of the most explosive players at the position in college football. If he went up against lesser interior offensive linemen — and he saw a lot of them — it was game over. That, however, didn’t fly against the one NFL-caliber offensive line he faced in 2019 (Oregon, 51.3 PFF grade), and it isn’t going to fly at the NFL level, either. It’s still a massive strength to have, but he needs more moves to pair with that.
