Last bit on Parsons.
I keep seeing the comparison of Jaylon to Parsons, but it's absolutely apples-to-oranges.
Parson has just played two years at linebacker. He was a running back and defensive end in high school. He's still learning the position and his ceiling is still incredibly high as he continues to develop and learn the nuances of the position.
Jaylon is who he is.
Jaylon has played linebacker his whole life; he was a linebacker in high school (won the Butkus award for best high school linebacker); he played linebacker all three years at Notre Dame; and now he's entering his fifth NFL season (of actually playing). He's not suddenly going to evolve as a linebacker and start taking on blocks, making the correct reads, stop biting hard on play-action/motion, suddenly start giving consistent/maximum effort in pursuit, et cetera.
Again, Parsons may be an immature nut job and for that reason be taken off some teams boards. I can't account for that because I don't know the verifiable truth behind some of the allegations. However, just in terms of a football prospect, he'll likely be one of the top defensive prospects possibly available at pick #10 at a position I feel is a real need.
