Snow is extremely legit and I said it last year when people were ragging on the D without being able to see the significant roster holes he was working with.
But, 8 consecutive draft picks spent on the defense including two top 10 overall picks and signing last year's 3rd ranked sack artist certainly haven't hurt efforts.
Rhule is clearly trying to build the Panthers the same way he build Temple and Baylor - dominant defense paired with decent offense. I know we can field a competitive team that way, but I'm not certain we can compete for titles that way. We shall see.
