Hos,
I'm not going to get into it like some of these other guys are with you, however, 2 things you brought up that can't be told from a still picture....
At the time of the picture, Q's arm is not locked or anything, yet how do we know that he wasn't in motion to get it just like Vinnie's.
You mentioned the height of the ball.....yet we don't see the height of the runner, so this would be impossible from this still picture, to determine if it was the correct height or not.
Also. the angle of the ball.....where is the runner? It would be much easier to tell if we could see the runner to determine if this was incorrect, we can't tell if the runner is runningto the left or anything OR if Quincy got the ball turned the correct way for the RB. BTW, I highly doubt that there is ANY QB in the NFL that gives the ball to the RB with the point hitting them in the belly.
Analysis is good for a point in time....with this I agree with you, but analysis without the ensuing pictures or more information is only as good as the period of time in which the picture was taken......which is only a split second.
For the record, your analysis is correct with what is in the picture, but we all know that we need more info. to determine if his mechanics are truly flawed in this play.
