Being a Colts fan I watched the game also.
I liked what I saw, he didn't seem to have the "deer caught in the headlights" look about him that you usually see with a rookie quarterback. The game didn't seem to be to fast for him to deal with.
A couple of times he was getting real pressure from the backside that he seemed to be able to feel and make good decisions.
He ran a little no huddle, not much, but it didn't hurt them much, I expect to see much more of that in the future.
His throwing accuracy wasn't bad, it could be better and I think it will get better.
This years Colts are a completely different style team, they are alot bigger across both the offensive and defensive lines and I for one say about freakin time. It was especially nice seeing them picking up 3rd and short by going right up the middle.
