I think totally dependent upon this upcoming season, it's Garrett or Holmgram.
The ball is entirely in Garrett's court though. With success he could be our coach for a long time to come. But fail;
2009 failure and I think it's almost a given that it becomes Holmgram in 2010. A respected, growing friend of Jerry's, and the one person with proven ability to rein in a QB like Romo, as he did with Favre making him a super bowl qb.
Shanny I think is an unrealistic flavor of the day joke. He is not qualified or ever done a thing that could be considered spectacular. He gets really angry and his face turns red, some people like that, but that's about all he's good for.
Cowher I think is someone Jerry would not want to work with. Yes he would be good but it would be just like with Parcells and the media taking direct aim at us over this. The circus would return.
Though a wild card I believe that none are mentioning is...Herm Edwards. Herm is what the late-Chiefs owner wanted to take over his team and run it. Now it didn't work out there, but one can't deny the degree of faith that was placed upon him, nor the very close relationship Jerry once had with their ill-fated owner. They were neighbors,, and friends. And in so, I wouldn't be shocked if Jerry at least considered this as an option. He would also be very good for the Cowboy's image.
