He was good and bad which I expected in his first NFL game. I think you'll start to see more good plays than bad as he goes along. Only time will tell but I give his performance a C+.
He needs to avoid staring down his receivers and looking at option 2 and 3 before tucking and running. He did look comfortable and in control of the offense which is sometimes the hardest thing for a rookie QB.
Have to say this was my thought as well.
I see a fair amount of use of the words "impressive" and "solid" in the headlines, but I wasn't left with that. I saw a guy who took off too quickly, or too late, and in between was not looking downfield. He went with the short safe throw every time it seemed. Maybe that's ok for a rookie's first preseason game with 2s and 3s but there were young backup QBs who had better performances thid past weekend, including Griffin, Thomas, Bortles, Kellen Moore (in the same game) even Austin Davis.
