Good break down. I think Tua had a solid game.
I really would like Tua to get more assertive on his throws/decisions. Always seems on most the ugly throws/decisions he is over thinking and not just playing. Two examples were the play that was almost picked, the guy was open right away Tua looked at him hesitated and then threw of balance and late. On that he needed to throw right off and after not throwing just accept to you missed the guy and air mail it out of bounds. The second was the underthrow to Carcraft. Again he looked hesitate to set right of and throw then looked like well I will run, but then decide to throw last second and out of sync. He need to decide am I running this play or passing and then commit to it. He looked like he never really made a decision and commit to it. Result an of balance out if sync pass.
Like the TD to Waddle, saw it, commeted to thr throw and zipped there. Like the guy mentioned he shows off a plus arm on that throw. To me the throws that look weak or float are the throws that he is not 100% commeted to the throw from a mental point.
I really hope he gets more comfortable in this O (it is new) and regain some confidence/ swagger.
