A few quick thoughts on Nkemdiche:
I have high hopes for this kid, but his red flag(s) are very concerning. First, the high hopes--even if he's only as good as Dockett during DD's best years, that's still a significant improvement. Not just to our defense, but our team overall. The hope though is that he's special. Somewhere between a DD and John Randle (that's a huge swath of real estate to work with).
The red flags, however, outweigh such lofty expectations. The pot thing is overblown, but I have to say, I've never walked through a plate glass window while stoned. I'm pretty much a munchy and couch kind of dude. But it's his lack of motor that concerns me most and the fact that even coaches who love the dude say he took plays and whole games off. First of all, even if he had a high motor, that doesn't always transfer to the pro's, where play is more cerebral and nuanced. If you have to think, your motor is stuck in neutral. Many rookies just shut down with overload. Nkemdiche isn't even like that, he took plays off when it was easy. In the NFL it's never easy, these dudes are feeding families (and apparently a large entourage).
That's two issues, two flags, for me: lack of judgement (not by smoking pot, but by walking through a window and falling 3 stories) and lack of motor. People say oh but TM was rehabbed and doing great, and I agree, he's a great success story. But TM had what Nkemdiche doesn't: In college (and now), TM had a motor and played football, constantly, no matter the opponent. TM is a machine on the football field--he cares about the game of football. Could be you and a few buddies playing, and he's going to bitch all night and probably next week that he missed a pick 6. Anyone get the sense Nkemdiche is like that? Too early to tell, but even soft-spoken Fitz is like that.
The worst thing you can be in football is inconsistent. Motor/effort one day and disappear the next. One game you think (as a coach), yes, he's finally got it, and the next he disappears entirely. One day he's awesome and killing double teams and the next week he's getting destroyed by identical formations.
Nkemdiche gives me flashbacks of Albert Haynesworth.
(The irony, of course, is that DD hated Haynesworth, so if Nkemdiche fills that role he'll be wearing DD's #. That's what happens when you go to SF, God ends up hating you)
