Personally, I think he just throws a much more accurate football this year. Maybe it's because of a better line, maybe it's because of a better run game. Whatever it is, it's happening. I can't ever remember feeling this confident on 3rd downs, especially 3rd and long. I'm sure the stats will show high completion %'s at times in the past, but it seemed like we threw so many safe 3 yard passes to Provo. That little TE out play rears its head here and there, but maybe once per game now. We throw down the field much more this year.
He also puts more loft on the deep balls now. Which leads to some underthrows. But as we've seen, underthrows have a better chance of being caught than overthrows. Better chance of being intercepted too, but I'll take the good over the bad (DBs at a disadvantage, if they were so good at it, they'd be WRs). Past few years, it seemed like he tried to make the perfect throw with no chance of INT. Which meant nothing deep ever worked.
I'm encouraged with his development, because I will take that to mean that this staff can develop QBs. Gravy.
