It's obvious he's gong to flop. Last season was an aberration that looks OK on paper only if you carefuly confine your scrutiny to the W/L record and don't look at the team's actual performance at all. He's reduced the cycle time by cleaning house before his ass is really on the line. By doing so he's clearly hoping to shoot right past the traditional firing of the head coach and slip into whatever uncharted territory might lie beyond.
Uh.. who did he "let go" to fit "cleaning house?" The only person that was let go was the TE coach and the equipment manager. Morris went back to Tampa Bay for better money. Washington got a better offer at Mississippi. Horton went to become OC at Air Force. Morris and Washington personal issues probably played some role in that. That leaves McGriff, who bolted for Miami, Boustead who is pursuing a graduate degree at Florida, and Shorty, the equipment manager that may have retired, no one is saying anything. While you can say "Let's just look only at wins and losses and ignore performance" (which BTW, on a coach's resume, the performance isn't so much a big deal as winning games) you can't assume these changes are part of the assumption he's "cleaning house". If you have error in your first assumption, and make many more based on that first one, you increase the range of your first assumption error exponentially. In other words, it's wrong to assume something that you can't back up in the first place.
On the other hand, it's nice to see how many people bite on your assumption and carry it across the world.
