Of course, in his six seasons at Tennessee, Bruce Pearl never got past the second round.
Not saying that he isn't a good coach...but that the ingredients also have to be right.
To make the Final Four, regardless of who is coaching, you need three point shooting, defense, and a few biggish guys who can rebound, etc.
While, on average, a coach reaching the Final Four has 10.4 years in...some, like Ollie, Shaka, Mike Davis...have done it on 2.
John Belein, Michigan, took 34 years, Altman at Oregon took 28 years....Jim Calhoun was a HC for 27 years when his time rolled around in 1999.
