Interesting replies, guys, although the only one I'm buying here is Bill Belichick. The others mentioned, while maybe not the "yell and scream" type, are still Type A personalities, IMO, and Shula does not seem to be.
Joe Gibbs, for instance, is not the type to ream a guy out for a mistake, but he still demonstrates a lot of intensity, is assertive, and--more generally--seems to be a born leader. I simply do not see those qualities in Mike Shula. To be clear, that's not to say he can't succeed--I simply can't think of many coaches with his apparent personality that have been particularly successful.
