I think Bob was slated to be the starter this year because the organization needed to find out if the man could learn to play QB in the NFL. Personally, I think Jay probably would rather start Cousins or McCoy--guys who can at least operate competently today within the structure of a basic NFL passing offense--but understands that the organization invested so heavily in Bob that to NOT take one more chance, healthy and in his second year in the system, would be a mistake. Bob has a legit NFL arm, and even with the injuries presents enough of a running threat to make NOT giving him this offseason, camp and preseason, to see if he can take the next step toward becoming an NFL QB, was not a smart organizational decision.
One can disagree with that decision, but not assume that means it was forced upon the football people by a "meddling owner." Who was in the room making that decision? We don't know for certain, but it's fair to assume it included Snyder, Allen, McCloughan and Gruden. And no one here has any idea how that discussion went, or how the ultimate decision was made to head into camp saying publicly that Bob was the guy. But given the investment in the kid, and the raw physical potential, it was and remains a defensible decision to have made, regardless of who made it.
Some apparently are convinced it was Snyder and/or Allen forcing the decision down Gruden's (and presumably McLoughan's) throats, and that that signifies nothing has changed. I won't try to disabuse anyone of that because we simply don't know. It MIGHT be true. Or it might not. I choose not to pretend I have knowledge I don't, and am a very curious and interested bystander watching how it all plays out.
