Lol what did you guys expect??? Seriously, it's the teams first time running a completely new offense in a somewhat real game situation. It takes time. I don't expect the team to look the same on gameday when we play Washington in September as we do today. With that said shut up and watch the game...
While that is true, I expect that when a D1 QB throws a pass that it goes where he intended it. Laviano seems to have difficulty throwing long and Rettig seems to have some general accuracy issues on occasion.
On top of arm strength and accuracy you then have knowing the playbook, mastering the system, making great pre-snap reads and audibles, communicating the play to the team, reading coverage, decision making, escapability, ability to run the ball, ability to take a hit, durability, not fumbling, etc etc etc.
But of the two, I haven't seen Rettig's occasional inaccurate throws result in ints. He doesn't seem to be "wild in the strike zone", to mix metaphors. Meanwhile I think Caroo's ability to comeback and compete for the ball on underthrown long balls has resulted in Laviano looking like he can throw the deep ball. I don't think he can. I think opposing teams will know that he cannot and they can then go tighter on coverage on the short and medium pass zone which will help in run support situations as well.
Bottom line: I think we need to see much more of Rettig in game situations order to know who is best. And maybe the new guy will be obviously better than both. I think we can trust Ash to make the right call. he has no "baggage" in this area, unlike Flood who, seemed to me, was trying to differentiate himself from Schiano is picking a QB and sticking with him no matter what. I think Ash and staff will make the right call, even if it differs with my relatively uninformed opinion.
