Charley Casserly was a lame duck G.M. during the 2006 draft. I highly doubt he had more influence or power over a first time HC who was looking to build a team in his image. Houston had nothing, but crap draft after crap draft before Kubiak showed up, so I think it's pretty obvious who had the final say so in that room.
I mean we're talking about a man who spent a 2nd round pick on Tony Hollings and traded 2nd and 3rd round picks for Phillip @#!%ing Buchanon (when Al Davis lost his mind and was making bone headed decisions, he was still able to take ol' Charley behind the woodshed).
The only reason why Casserly was even in the room during that draft was because Kubiak was given complete control and was allowed to hand pick his own GM.. after the draft, hence why Rick Smith (from Denver) is here. Kubiak was given complete control.
I'm tired of hearing about how Kubiak signed off on Carr and talking about how he could win with him... Like anybody here has never lied on a job interview before. The #1 requirement to becoming the Texans' head coach was the resurrection of David Carr. If Kubiak told McNair that he couldn't win with Carr, I highly doubt he'd be here.
