Anyone can tell you that 2019 NFL draft prospects Nick Bosa and Quinnen Williams are going to be good players at the next level. Where draft evaluators separate themselves is filling out their rosters with quality starters on Days 2 on 3.
Using Pro Football Focus grades -- we grade every play of every game of the college football season -- here are 10 prospects our advanced staff and draft analysts love more than the general consensus. All statistics and rankings below are from PFF.
David Long, CB, Michigan
Position ranking: No. 4
Overall ranking: No. 33
Few cornerbacks have been stingier than Long since we started college charting in 2014. In 595 coverage snaps in his three seasons at Michigan, he was targeted 60 times and allowed all of 18 receptions -- the vast majority of which were throws underneath -- for 130 yards and a passer rating of 24.3. On targets 10-plus yards downfield, Long yielded only four completions on 29 attempts for 59 yards while breaking up 13. Those stats are out of this world.
In his combine performance, leading the 3-cone and short shuttles, Long showed that he has the athleticism to translate to the next level. Teams might take him off their boards entirely because he is shorter than 5-foot-11 with less than 31-inch arms, but if they do, they'll miss out on a great player.
