I've been critical of Painter at times, doesn't necessarily mean I want him fired (OK, maybe I did say he should be fired after the FDU game....) but, I'm also not of the belief that Painter is the best Purdue could ever do. Nor do I believe, and which is supported by data, that Painter is a strong tourney coach in March.
I think Painter is a solid X/O coach, wins a lot of games Nov-Feb, is becoming a better recruiter, but very stubborn and not flexible in his strategies or in-game adjustments.
It'll likely be a few years until we know whether someone out there can take Purdue further than Painter has.
