I honestly don't know what to expect from them. It could be a good season or a train wreck or virtually anything in between. Too many variables.
If Prescott plays more like he did in preseason than a typical rookie 4th rd pick QB would play, they could be pretty good. The rest of the offense is loaded. I am in the camp of hoping Prescott is good enough that they have to leave Romo on the bench when (or maybe even if) he is ever actually ready to play. The special teams should be pretty good.
On defense, I like the DT rotation and Byron Jones at FS, but the rest of it is question marks and a strategy of hope. Sean Lee is a great player when healthy, but he's already not healthy and that's after playing only a handful of preseason snaps. I have no faith in Brandon Carr and while I am encouraged by how Claiborne looks and played in preseason, I've learned not to trust him either. The DE situations looks pretty bleak for the first month of the season and could be a major headache all yr even after Lawrence comes back unless others step up.
I'm resolved to just sit and watch and hope for the best.
