JD - Me thinks that you are too pessimistic.
QB - it is NOT possible for a QB to have a worse season than the one we experienced last year. Simply not possible.
RB - return productive backs
TE - return productive TE
WR - not possible to have worse WR than we had last year
OL - should be actually good helping the RB situation
There is simply no way that an offense can be worse than last year. As a matter of simple fact, if it looks anything close to last year, I would without question remove Ferentz as coach and make a case that it was a for cause termination.
As for the D
DL - can't be worse
LB - return all starters (granted they're not great, but they return)
DB - well.....we'll have to see.
This doesn't mean that there is serious talent on either side of the ball, just that in no way should we be as bad or worse than we were last year.
You have to figure/hope a couple bounces go Iowa's way this year. Anything less than 6-6 is a major disaster, but let's be honest, when you have the history and investment in your program that Iowa has, going 7-5,4-8, and 6-6 in a three year stretch is a major disaster.
