Most of those that question House either don't understand him, are jealous of his success and status, and/or can't find ways to combat the insane amount of research and science behind his work--so they knock the guy. Having met Tom a number of times, I am ALWAYS impressed by his willingness to talk pitching with ANYone, working at any level. In addition, Tom is a genuinely personable and fun guy.
Coaches in any area of any sport could take a cue from the tremendous amount of effort and passion Tom puts into his work. Greatest thing I can say about Tom is that I have never seen him "bigtime" anyone--would that that could be said for a myriad of other coaches whose credentials and passion don't begin to rival Tom's.
