I'll agree. I'm as big'a Bo-backer as anyone, but if we bomb the next two years, then yes, by then it will time for a change. I was a Callahan supporter up to the '07 USC game. The programs was taking steps. Sure '06 ended badly, but we were very competitive with two very good teams (Auburn was the only team to beat that season's National Champion). But when the USC game in '07 came around, and then the near Ball St. disaster a week later it became clearly evident it just was not going to work out. So, I joined the crowd and got my pitchforks out too.
I just believe in patience. Cally only got 4 years, and Bo is in #5 and I'm asking for more, but with Cally is was obvious. There was plenty of evidence. With Bo. Not YET. If we finish this year with the status quo 9 wins, then yes, two more years should be a reasonable guarantee. But we also have to define exactly what a "flop" in the next two years would be...
With the scheduling and a veteran offense, I'm gladly to say that anything less than a division championship would be borderline unacceptable. It would be tough to require a Big 10 championship simply because of what Ohio St. is probably going to be. That's something that could vary througout the season. Requiring a BCS bowl and/or MNC would just be ludicrous. As far as wins go, any thing less than 10 win regular seasons the next couple, could spell bad news. I hope not, but it could.
I am in the same boat as you are with Bo...If we can finish with another 9-10 win season and a win in the bowl game, i will be happy. Next year should line up good for us with our schedule and if he lays an egg in a couple games, then I will start doubting him as a coach.
