He's not wrong. If you're undersized, out manned, out gunned, or any of the other 500 descriptions of being overwhelmed by your competition... You better figure out how to gain an advantage. And that is never going to be by doing things the same way your competition does...
This is why people break out guerilla tactics in combat, jiu jitsu in a fist fight, moneyball in MLB, or whips and nipple clamps in the bedroom... To gain the upper hand when you are overmatched. I don't really think it's an argument that can even be had when it comes to Mississippi football. If everyone else is going to zig we have to zag. We need to be an outlier.
The argument is not whether Goat is right. It's whether Lebby is going to do stuff different enough and can run his program well enough to win. I think so much of college football has gone to a spread/hurry up offense these days that it's actually the norm, much like moneyball, analytics, and guys hitting .217 with 24 HR, 130BB & 197 K in MLB is the norm. Jake Mangum is the outlier.
What style of offense (and defense to some extent) is right, no idea. But it's not the one similar to everyone else's.
