I've been very busy with work (4 AM-5PM), got home, checked NFLGAF quick (before Profootballtalk) and heard the news.
As Doorman said it was a pretty weak year as far as head coaches are concerned and we possibly lost out on O'Brien waiting for Whisenhunt (though who knows). I just don't see anyway the Titans are a better job without a QB, a ridiculous contract to a RB and no recievers to speak of. Not only that but we have a higher draft pick at #10 than the Titan do at #11.
I think it probably came down to how the defense was going to be run. If he wanted to run a 3-4, there is no way you come in and change that right now when we just drafted Ansah as a defensive end, and have Suh and Fairley at DT. Suh will get the contract extension he deserves and we'll ride Fairleys rookie contract till the end when we eventually get his replacement. I honestly believe that is probably the reason he choose the Titans over us.
On offense we have a proven Quarterback, Calvin Johnson, the #10 pick, two solid RBs, one of the best offensive lines. On defense we have Ndamakung Suh and a great supporting cast of defensive lineman. I don't care what anyone says we had a better coaching opportunity in Detroit if he wanted to win immediatly.
His loss. He can go to the Titans, draft a QB with no experience in the NFL, a shitty cast of RBs and WRs (other than Britt who will probably be traded) and get fired in two years. Bring on Jim Caldwell and bring on the draft.
