Top-rated \ best defensive prospect for this draft is Micah Parsons.
Viewed close to 30 mock drafts to date; 1st defensive player picked-predicted off the board has been overwhelmingly Parsons. The highest I've seen is him going @ 7 to Detriot; most of the selections are the LB going to Denver with the 9th pick.
Only four times did I view another defensive player going before him - CB Farley @ 4 to Atlanta (by a Falcons homer blogger), LB Jeremiah Owusu-Koramoah @ 9 to Denver, and CB Surtain twice - again to the Broncos.
If the Cowboys select Parsons as the no. 10 pick as Redball Express predicts - that will be a surprise...and shocking.
99% chance that Parsons, or one of the top three corners (Farley, Horn, Surtain) will be the first defensive player selected in the 2021 draft.
In summary- Micah Parsons is not a sleeper .
