Difference between those who recieved the sum of their education on campus, and those who did some learning wearing Kevlar (though I do go back to the steel pot days). You either get it, or you don't. With few exceptions, those who think like Petrino are simply clueless. If it weren't for the fact that they'd last about 30 seconds, I'd love to find a way to put them in those soldier's and marine's shoes for a few days. Then I might have some respect for their opinions on how it is all so wrong.
