I don't think it's entirely unrealistic to expect two pass TDs per game for the rest of the season from Josh. He's done it each of the past 6 weeks (I think).
I know one thing, he has no INTs since week 4. Zero.
So, we'll see where this thing goes. But he IS already proving himself to be a franchise guy, in my opinion. He's certainly better than any QB we've had the prior 20 years, and I think he's got a chance to end up the best out of his class if he keeps moving at the trajectory he's on.
