Same here. Our DB's may not have been as bad as they looked all year last year.....but we'd never know it as the opposing QB's always had all day to choose a receiver and throw. Even the best DB's can only cover effectively for maybe 4-6 seconds.
I think its safe to say we were extremely weak on D period...
DL lacked everything (run stopping and creating pressure.
LBs were weak and very slow. The middle of the field was wide open all the time.
DBs were often literally 15 yards away from the receiver downfield when they caught the ball (see OSU, CU, KU, Mizzou).
We have a major overhaul at all positions. I will be happy if we can even get slightly better than last year considering we have so many returning players.
