I think he's already proven he's top 10, and I think by the end of this season, we may be talking about him in that upper echelon, with Manning and Brady. I would already take him over any of the 2nd tier QBs, like Bulger and Brees. Until he wins several super bowls, nobody will say he's better than Brady, and nobody is better than Peyton, but if he throws 30+ TDs and keeps up like he is, even the blind of haters will have to give him the respect he deserves.
I don't know how anybody can not get with Romo. He took the hard road getting to the NFL, he works harder than anybody else, and he just has fun playing.
