I disagree only slightly with the foregoing, but to my mind significantly.
Making it only to the Sweet Sixteen and losing there is an unsuccessful season.
Making it to the Elite Eight is an acceptable season.
Making it to the Final Four is a successful season.
Making it to the Championship Game is an exceptional season.
Winning the National Championship is an extraordinary season !
This seems upsurd, considering we have only made the final four 9 times since the tournament expanded in 1985 to include 64 teams. That is 9 times in 34 years. Are we really going to say the most successful college basketball team in history is only successful 26% of the time?
