He'd deserve more credit if it was one good game, rather than one good quarter. Is Tua more represented by the other 7 quarters than the 1 quarter of last week's game?
I think Tua is more defined by the NE game where he was more of a game manager, having thrown for 1 TD. I'm willing to cut him some slack and dismiss the first three quarters of last weeks game. That 4th quarter this last week, however, is the real outlier for him.
It's a possibility that what has held Tua back, if anything, is from the neck up. I've heard some talking heads suggesting that McDaniels has worked with Tua on the mental aspect of the game, helping Tua settle rather than trying to push or force a game. These heads said that perhaps that is what happened in the 4th quarter last week. We'll see.
