Fair question. Two things are a concern. The first is what it is with every rookie QB who comes out and has a great rookie season. Tape. As I said,there are those who know more than you or I that can expose flaws after having time to review it. Ala Cam Newton, hence the comparison. The other is what SuperPunk mentioned. He exposes himself far more than most QBs do to big hits therefore risking more injuries. Also, if part of his game is relying on his mobility, which we all know he has remarkable speed, and that is taken away because of an injury, how will he respond? It's really more, at least for me, still an unknown. Some on here think he is the greatest thing since Red Grange and are anointing him as such. The premis of this thread was trading Romo for Griffen and would you do it. For those reasons I have tirelessly laid out and because we simply don't have the known quantity, I said no to the trade. I would rather have a QB who I know what I have and can plan around, than one who will be a potential liability if there are major flaws in his game that are exposed.
