Yeah, Tua deserves way more credit than anyone gives him. Not many/no other QB in the league right now can get the ball out fast enough behind that OL (or are expected to get the ball out as quick) and he's showing how important that is to the offense. It's all about reading defenses, calling your own protections, etc. and few QB's are as capable of it. Dude is literally the offense and he got to do it with an OL that will not give him much time to throw.
Now I'm really curious to see what he can do behind a GOOD Offensive Line.
