To the degree you're even right (and there's some truth to what you're saying), this is all by choice -- both past and current.
I agree that we'd all do well to realize that we're not the program we were 25 years ago. But I also think that a series of good decisions can turn things around -- just as a series of bad decisions got us here. And I don't think having some guarded impatience in that is a bad thing. What it shows is absolute commitment.
I don't think that Michigan basketball is a good parallel for us. They're a football school and don't have nearly the history or tradition we do at basketball. They've had some great teams, of course. But it's just not the same thing.
Honestly, I think a better parallel for us is Alabama's (pre-Saban) football program. The Stallings years were up and down. Then they went through the Franchione debacle. Dubose got himself a 4th year only by going 10-3 in his third. Shula was awful -- and he got 3.5 years....but I'd bet anything they wish they'd pulled the trigger after the third...especially after the sanctions.
Saban was given one year on a pass -- he was 7-6. And, from there, he's never looked back. He didn't need to -- even though he didn't have a roster full of "his players."
If we allow Archie (or anybody else) more time, after 3 bad-to-mediocre ones, then we're making a declaration that bad-to-mediocre is essentially good enough.
I agree with you that 2 isn't enough. But 3 is.
