I think Salisbury had the best take on it, when talking about Bledsoe after the JAX game. Yes, he can be an idiot at times, but he's a former QB & occasionally makes sense.
His thinking is that Bledsoe gets until Halloween to either improve or get benched. That's a fair amount of time to determine if he & TO can gel, since Bledsoe is already doing well with Terry. It does make sense--he's probably going to have a decent game against the Texans, & the Giants will make for another test. If he passes that, he's probably in. If not (or maybe he gets until the Panthers game), then he's out.
I'm torn on this. I do think Bledsoe should have a chance, & realistically if he does get demoted, he's not going to become the starter again. Plus, TO's hand is healing, so the two of them have two home games to get better synched. You can't start Romo, see how he does, then bench him--once he starts, he's it for some time to come (even next year). I think Bledsoe is classy enough that he'd stay as the backup out of loyalty to Parcells.
However, if Romo is going to start at some time this season, the Texans game would be a logical one. A reasonably easy opponent at home in front of a supportive crowd is a good intro. Looking at the schedule after that, I don't see an easy place to make him a starter, except possibly the Arizona game. I seriously doubt anyone wants to see him make his first start either at Carolina or at Washington. (Altho, with the way they've been playing, that might not be as tough a task as it looks right now.) Even at home against Indy--I don't see it. I suppose if Bledsoe does poorly against the Giants & Carolina & Washington, then the season is pretty well tanked anyway, so no harm in starting Romo. Right now, I still think Bledsoe is the better chance in those upcoming games.
TO may not like it, but he has to take a bit of the blame (not for the underthrows of course) for not getting a lot of throws. He didn't practice all summer, plus he missed most of last year. Does he really think Bledsoe is going to throw to him constantly when Terry can catch anything thrown in his vicinity? He was warned from Day One that he's not going to be the star here--he's one of several good WRs & TEs. He needs to heal his hand, stop dropping the passes that do go his way (as in the Tennessee game), & spend more time synching with Drew. He also needs to realize he's past his prime. He was foolish to blow his chance with McNabb, but this is his reality--he's 33, he wanted money, he's with a team that doesn't pass a lot, he's an aging prima donna that few teams want any more, & he's not going to be treated like a superstar anymore. There's no "TO ratio" for him.
