I don't think he needs as lot of time. He needs coaching. He is plenty good against the run and is versatile. They can use him from day 1 in different ways. Strength isn't a problem for him.
His is raw on pass rush moves. I see him in a rotation the first year with Gregory and Aldon and coming into his own in the 2nd year. That's pretty much par with most DE's. Very few come out of the gate with 12 sacks.
Plus I wasn't to see what Gregory has anyway. He could get some snaps on the other side backup up Lawrence as well.
I see a kid when blocked by Tackles. Its a mismatch. Its like a kid trying to play with grown ups.
Even against RBs he gets manhandled. And a lot.
He ties to use hand teqnique but looks rather silly by doing so. Spin moves etc going nowhere.
In the running game teams tend to run to his side. He just gets demolished.
He doesnt seem to recognise plays. Just bad.
Sticks to the scheme much more than going for the ball.
Too often i watched him sticking to his man when it was clear for about 3 secs that the play was going the other way.
I think he has some upside. But he needs at least 2 years of grooming before you can use him in a good rotation.
What he is good at is dropping of in coverage. So i'd rather use him as a LB than at DE.
I wouldnt take him even in the 4th round. I dont have time to wait for 3 years to eventually have a player.
