There is absolutely no factual information about TA that should lead us to believe he's going to all of a sudden become a competent passing QB in year 4 as a starter.
Lets remember....
Tommy was #2 in the nation in interceptions last season with 16.
We are replacing starters from an OL that wasn't particularly good to begin with in 2015.
Virtually no consistent production in the rushing game last year as a whole.
Replacing 2 NFL drafted DT's. (Not upgraded yet)
Still young or average DE's. (Parrella could be enough to make up for lack of talent)
Secondary that was 7th worst in the nation in yards given up 290 yards per game. Company with Kansas, Indiana, Oregon, and Kansas State.
Play calling that was cause for remotes being thrown into tv's, windows, walls, significant others, and pets.
We have no factual information to believe NU is in contention to win 10-11 games yet. It can happen but the facts are holding against it.
Best case
10 wins
This requires
TA to have no more interceptions than TDs
A healthy DPE
Someone to play above average at DT
Worst case
5 wins
Some possible causes
TA injury
Injuries on OL
Coaching staff continues to lose in the last seconds of the game
Poor IB play
TA didn't have more INT's than TD's last year. Still went 5-7
