The main thing is his progression throught the season so far, he is developing right in front of our eyes. His reads are way better then Rex's anyday, and have you ever seen Rex read before a snap like Orton? I doubt it, I been watching Rex since he started, He would always stick with whats called, And let his arm strength try to overcome his reads. Orton on the other hand seems to have a knack for addressing what the D gives him, and if the play dont fit he changes at the line. I like this style much better then rex's anyday. But there will be wrong audibles iam sure as we seen already, But its a learning process that has to be done.
