Unreasonable and basically unachievable -- anywhere. 3 FF's in 5 years?? Haven't read through this thread but don't think we ever did that before, so confused as to how in the world doing so, for the first time, would be 'back.''
For me, conference championships absolutely matter. They -- along with regularly competing at the top of conference -- are a much better barometer of how good a team/school is than its MM runs, which, clearly, are 1 and done games in the 'madness' setting of the tourney. Winning well regularly in conference is the route to a championship, in any event.
I'll go with regularly competing at the top of the B1G, with at least 1 conf championship, and consistent NCAA tourney runs, no NIT's, with multiple SW16's and at least 1 EE over a 5-6 year period (with the assumption that level of success continues forward)
