No matter how you shake it out, he's a rookie. And it's his first game in the NFL.
So I imagine the looks the Rams give him will be to confuse..... and sometimes they will.
He was an accurate thrower in college.
Hard to imagine he'll have the support of a run game.
So I suspect it'll be a tough day for him.
Rams have enough speed to keep him bottled up pretty well.

Glad we're not playing against Fitz. That guy is a good QB who can get really hot; I find it fascinating that the Dolphins are starting Tua. Why not let him learn this first year from Fitz and then start next year?

I can only guess that they think he's ready.
Playing a QB for the first time can be difficult for the D because you're not quite sure what a guy can do and not do.
