First of all, I'm not a Marquette basher. Milwaukee born and raised, MU has been my home team ever since I started paying attention to NCAA basketball. Now that I've got that out of the way...
I present empirical evidence that Tom Crean is a mediocre coach!
Over the last 5 seasons (post D. Wade), Crean's Golden eagles are a combined 14-26 against these "marquee" coaches:
1-1 vs Mike Krzyzewski (Duke)
3-6 vs Rick Pitino (Louisville)
0-2 vs Jim Boeheim (Syracuse)
0-2 vs Lute Olsen (Arizona)
2-3 vs Bo Ryan (Wisconsin)
1-3 vs John Thompson III (Georgetown)
0-2 vs Bob Huggins (West Virginia/Cincinnati)
2-1 vs Jim Calhoun (Connecticut)
0-1 vs Tom Izzo (Michigan State)
5-3 vs Jamie Dixon (Pittsburgh)
0-2 vs John Calipari (Memphis)
I left out a win against Bob Knight's Texas Tech ...
