People forget this is college football. Kids develop from year to year- I wouldn't look at anyone's previous production as they have an extra year in the weight room and also under this scheme. We still don't have all the pieces- but I bet the pieces fit better than last year's.
I don't care about last year- the D stunk. Yes, this is a rebuild- and I still like what Crocker's D did at Villanova. Given the right players, he can do that here as well. I like the DB's- yes, I like them. They are young but we have enough bodies to make things happen. I like the LB - last year's group was too slow for this D and people made Junior Joseph out to be the Alfred Fincher. Guess what, he wasn't. No knock on him, but the fleeter of foot linebackers will help out. Who was our best blitzing linebacker- Beavers? He was a true freshman playing the position for the first time.
From a D line perspective- if you want your linemen to hold off the O line so the LB's can make the play, then we have the pieces. If you want the D line to disrupt and make the play, you don't have the pieces.
Overall, more familiarity with the D will help them play faster. Crocker was limited because the defensive backfield and linebackers couldn;t do the fundamentals - tackle the ball carrier or receiver in front of you. They had to play guys 10 yards off. They couldn't blitz from wherever because of this. While I am not predicting a Top 75 defense here- I know it will be better than last year. Players will make names for themselves just like those that proceeded them. Time to stop the doom and gloom and trust the coaches.
