Don't know what anyone sees in this offense. Looks like a scrum to me. People are in each other's way all the time. Rarely any holes in the middle. Rarely do they try to run outside, even with so-called "speed" guys. I mean, compare to the NE offense, where there's ALWAYS people open on one side or the other, always people with a yard advantage downfield, where nobody gets near Brady, and they all stay out of each other's way to boot. OBrien's offense looks to me like a clump of crap--nothing open, no space made or taken, everybody blanketed 9 times of 10, get 2 yards on any running down mostly. Something's not right with the offense, or the teaching & coaching of the offense, or the execution of the offense. And there's no imagination at work--never do we come away thinking, Where did that come from?
And OZ's problem is not only his inaccuracy. As everyone has pointed out, it starts with his movement which is very awkward, perhaps owing to his size, and then to his throwing motion, which is ridiculous for an NFL QB--the unnatural and elaborate windup, his vision of the field and his receivers is very slow and very poor, and he is, as you say, not very accurate. He's a whole bucket of problems in one 6 foot 8 inch basketball player.
