Well, UWBadger, you have to admit that Marquette is not a powerhouse program and success there at a national level has been spotty. MU did not make a Final Four for almost 30 years until he took them there in '03 - heck, they've made only 2 Sweet 16s since 1980. So Crean generally did a good job there compared to the average season.
I do believe Crean's recruiting will help Indiana get back in the top half of the Big Ten sooner or later, but it's not going to be before these touted recruits arrive (i.e., it's not happening for IU this year). Indiana was the de facto worst team in the Big Ten last year (although they did not have Creek, they were still really, really bad), so I am not expecting big things from them this year because they have almost the same group of players - I'm not saying they can't be better, just that I'm expecting something like 12-15 wins this year. If they have an NIT season, it would be a pleasant surprise. Most likely 2012-13 will be the first season when IU fans can expect to field a team that legitimately can challenge for the Big Ten title, but 2011-12 could be a top-half finish if the basketball gods smile on them (i.e., no significant injuries/suspensions).
