My two cents are that he is not reading the field at all. Beck said it perfectly when he said he isn't "seeing the field" very well. It's true. There are certain situations where he reads it well, or makes a good decision, but he has his bad moments too. I think it was obvious when he was.
Hell, even a good play was a bad decision. When Enunwa made that excellent catch between DB's. Great catch! But TA had Cethan Carter completely wide open in the middle, and he threw into double coverage. The defense played a lot of zone coverages. Some QB's throw well against (Zac Taylor and Joe Ganz threw excellent against those types of coverages, and TM throws pretty well against them too).
So, in conclusion, he just is not seeing the field well, and when he is hurried, he just hurls it at the first guy he sees. Freshmen mistakes, he knows he has to clean them up. The last one, he didn't even see the LB and he just threw the ball out there. It sometimes takes a bit for guys to know where everyone is. A lot of studying and understanding coverage concepts (and route concepts for his WR's). Something that he is struggling with and will struggle with. He'll learn those concepts and how they work against certain plays and such. Right now, you can tell they are just trying to get him to just run the offense. It's hard to teach all this at once to someone who was a natural talent in HS.
With that being said, the team seems to play extremely well with him as QB. The defense plays lights out when he makes mistakes. The WR's catch balls (ie. Enunwa must catch into double coverage). The RB's makes plays. This isn't about his ability, but the team in general has a "we need to play well for this kid" mentality or something. For that reason alone, there's upside to the kid. He's thrown 3 picks in each of the two games he started. Both W's. I am not saying it is because of him directly, but somehow, the mentality of the team is better. Maybe the game plan is better for them. The linemen love to run the ball, so a more run-oriented game plan might just pump them up more than the game plans for TM with a more pass happy approach (the one against Minn).
