He isnt overrated. He does throw a few bad passes here and there but overall, he is probably the best QB in the NFC.
I dont know how many times I've seen Romo make a play that he can only make.
He throws a few INT's here and there and those will be cut down once he plays a couple of seasons, but I rather have him you makes plays all over the place than a guy who takes the sack and then doesnt get that TD.
