That still remains to be seen. Right now, that answer is "no."
I didn't watch this game, but in recent games, it appears as if his throwing mechanics look like they regressed.
He used to throw with a mostly overhand motion, and you could see his hips and shoulders squaring up properly when releasing the ball.,
These days, it looks like he's trying to sidearm it, since sidearm throws are easier to make when your hips and shoulders aren't in sync.
His quarterback abilities aren't rotten, but they're certainly not anywhere near the top tier.
