Here's a good article from 2005 about Mike Leach that inadvertently highlights why he would be perfect for Ole Miss: http://www.nytimes.com/2005/12/04/magazine/04coach.html?pagewanted=print.

Mike Leach got extraordinary numbers with ordinary (at best) quarterbacks.  He found innovative ways to work with a lackluster offensive line.  Imagine what he could do with SEC-caliber talent.

Michael Lewis, author of the Blind Side
"Leach was finding new and better ways to extract value from his players."  

Jim Schwartz, Head Coach of the Detroit Lions
"They weren't scoring all these touchdowns because they had the best players.  They were doing it because they were smarter. Leach had found a way to make it work."

I don't know if he could run the exact same system in the SEC, but Mike Leach is a problem solver.  He knows how to work with what he's got.  If you've read Moneyball or Leach's new book, Swing Your Sword, then you know how important it is for disadvantaged teams to get creative in order compete.  We've been doing the same thing since the civil rights movement.  As Herman Cain would say, "How's that working for you?"

PS
He coordinates his own offense which will save some money.  We're going to need it since we owe Nutt a buyout.
