4, 2, and 24. I think these are reasonable, minimum expectations.
We got spoiled with some great teams and had some very impressive tourney teams. I think it is rather unrealistic to expect that consistently but having a top 10 team every 3 or so years is not exactly unreasonable either. Getting to 9 to 11 wins in the B1G should be enough to get into the tournament every year and I think that is a very realistic expectation too.
With that being said, I know we aren't exactly a traditional blue blood program in basketball, but we have access to talent and have resources to compete with them. There is no reason why a coach cannot sustain a tournament caliber team at a place like Ohio State. Sure, we will miss it every now and then with down years, inexperienced roster, and injuries, etc. but being out for two seasons with the way college basketball is structured today is rather unacceptable.
