If we end up escaping the season with a 10-8 Big Ten record and a Sweet Sixteen appearance, I think this stance would be pretty difficult to support. I don't guarantee that that will happen by any means, but it absolutely could. Sure it might be a little disappointing if you were hoping for 12-6 or better coming into this season, but it wouldn't a be a train wreck of a season. Others mentioned earlier, you probably shouldn't fire him after his best season.

I don't understand this at all. If Jerry Kill went 3-5, 4-4, 4-4, and 2-6 (with his 4th string quarterback) in the Big Ten with 3 bowl appearances in his first four years, would you fire him? Hell no. Sure basketball has a little bit of more recent success than football, but all that means is that our last winning Big Ten basketball record was 8 years ago instead of 10 for football.
If you fired Tubby then, you'd be firing him almost entirely based on about a month and a half of bad basketball. We lost 10 of our last 11 games in Tubby's fourth season, which sucks, but other than that there would have been pretty much no good reason to fire him. He got a 7 win team to 20 wins in his first season. He made the tournament in his second season. He made the tournament again in his third season with his two best players suspended for the season. If you say having Royce and Trevor on the floor is worth just two more points a game, that would have upped the regular season conference record from 9-9 to 13-5. With those two, we could have very realistically won the Big Ten. Not to mention that in his third season he beat more Big Ten teams than he lost to. For whatever reason, no one counts our Big Ten tourney run that year in Tubby's Big Ten record, which puts the team at 12-10. In 2010-11, we made it into the top 15 and had already beaten a top 10 conference opponent before we lost Nolen and Joseph and the wheels came off.
TL;DR Firing Tubby after the 2010-11 season would have been completely ridiculous. Outside of the bad skid to end the 2010-11 season, there was nothing to warrant his firing at that time.
