He does get excited (hammer/nail speech, etc.), but he doesn't prance and dance around like a freakin' nutcase. We should applaud that in him. He has his weaknesses. That isn't one of them.
I've never seen anyone as intense as Muschamp in those photos. He should join the WWE. He could be called The Coach. Walk out yelling at fans blowing his whistle in their faces, pointing and yelling at them.
Beckham runs out of bounds much too much for my liking. Reminds me of a certain USCw player who returned a Heisman.
Les is goofy, no doubt. But he's the lovable crazy uncle type (hell, you're probably seen as the crazy uncle, yourself.) Pelini is the crazy next door neighbor that you're afraid will hold his wife and kids hostage at some point after a bad day at the office.
Les is embarrassing. Goofy at times but doesn't excuse his continual embarrassments with time management. I'd rather pelini in my foxhole however. Les would be as reliable as Elmer Fudd and likely kill us both.
