QB | RB | WR | TE | T | iOL | DI | EDGE | LB | CB | S
-
-
S Ar'Darius Washington, TCU
The TCU safety may not even be 180 pounds, but he continually plays bigger than his listed size. Over the past two seasons, Washington has earned a 91.3 coverage grade, allowing only 15 total catches on his 35 targets in coverage.
-
WR Cade Johnson, South Dakota State
Johnson was uber-productive on tape against FCS competition, but it was at the Senior Bowl where he really shot up boards. Johnson left that week of practices with the highest grade in the one-on-ones working primarily from the slot.
-
DI Marvin Wilson, Florida State
Wilson came back to try and push his draft stock high into Round 1, but he may have incidentally torpedoed it in the process. He looked like a different player on tape this year and only earned a 67.7 overall grade after a 90.7 in 2019.
