re: Explain to me how Orgeron was an upgrade over Miles.

To my eyes, the current Tigers are among the best-coached teams around. Penalties and busted plays are down, kicking/special teams play has gone from poor to great, turnover margin may lead nation. Game and clock management angst has disappeared from discussion. Record has exceeded preseason forecast. Only a handful of teams doing better and they'll all be in the playoffs. What is lacking, hopefully to no one's surprise, is superior or Sunday-caliber talent on the offense. The line is mediocre and the skill guys are pedestrian. They're probably getting close to the most out of what they have and who they are. Miles' later teams had better physical material that suffered from poor grooming. These aren't things I know, just what I've seen.
