The win total that's the measuring stick needs to be defined in terms of whether or not tOSU is allowed to have postseason play this year. It's possible that tOSU won't get a postseason ban, and it's possible that one will be handed to tOSU but won't go into effect until the 2012 season.
8 wins probably won't be enough, even with a win at TSUN. 11 wins should be enough, even if there are 3 losses (14 games means a CCG and a bowl game).
If it's 9 or 10 wins, I think the overall season needs to looked at in detail.
Probably not good enough to be offered the job full time, if I were AD:
8-4 with a loss at TSUN, no CCG or bowl appearance.
8-4 with a win at TSUN, no CCG or bowl appearance.
9-3 with a loss at TSUN, no CCG or bowl appearance.
9-4 with a loss at TSUN, no CCG appearance and a bowl loss
9-4 with a loss at TSUN, no CCG appearance and a bowl win
9-5 with a win at TSUN, a CCG loss, and a bowl loss
Good enough to be considered:
9-3 with a win at TSUN, no CCG or bowl appearance.
9-4 with a win at TSUN, no CCG appearance and a bowl win.
9-4 with a win at TSUN, no CCG appearance and a bowl loss.
10-2 with a loss at TSUN, no CCG or bowl game.
10-3 with a loss at TSUN, no CCG appearance and a bowl loss.
10-3 with a loss at TSUN, no CCG appearance and a bowl win.
10-3 with a win at TSUN, no CCG appearance and a bowl loss.
10-3 with a win at TSUN, no CCG appearance and a bowl win..
10-4 with a loss at TSUN, a CCG loss, and a bowl loss.
10-4 with a win at TSUN, a CCG loss, and a bowl loss.
10-4 with a loss at TSUN, a CCG loss, and a bowl win.
10-4 with a win at TSUN, a CCG loss, and a bowl win.
10-4 with a loss at TSUN, a CCG win (B1G Title) and a bowl loss.
10-4 with a win at TSUN, a CCG win (B1G Title) and a bowl loss.
10-4 with a loss at TSUN, a CCG win (B1G Title) and a bowl win.
10-4 with a win at TSUN, a CCG win (B1G Title) and a bowl win.
I'll be hoping they stick with him in these circumstances:
10-2 with a win at TSUN, no CCG or bowl appearance
10-3 with a win at TSUN, no CCG and a bowl loss
10-3 with a win at TSUN, no CCG, and a bowl win
11 wins in any circumstances
