No, I'm not focusing on one year, I'm looking at the whole history of Marquette not just picking and choosing parts of it to support my argument. Marquette was a mid-major program when Tom Crean took over a bad team there, one that finished 14-15 overall and 6-10 in conference. It took him two years to build the program, then he took them to the tournament 5 of his 7 remaining years. Before his arrival, Marquette had only been to the tournament 7 times in the previous 20 years. Also they had only made it past the second round 5 times in 25 years. Despite taking over a bad team as a first time head coach, Crean also had a higher winning percentage than all but three other coaches who coached more than 1 year in Marquette history. His long conference championship was also one of only 4 total the school has ever won.
Of course it matters what the previous coaches did at a school if you actually want understand the context of the discussion. Then again, I guess it isn't important at all if you just want to push an agenda and don't really want to put any effort into supporting your position. Btw, it would have been kind of difficult for Mike Deane to have much tournament success considering he only made the tournament twice in his five years despite taking over a good team.
All that aside you never even touched my main point that none of the reasonable/viable replacements candidates bandied about have demonstrated Tom Crean's level of success.
