Don't get mad but I disagree... at least with using the play link you posted. I see the LB bearing down, unblocked, on the Scatback. At this level, that's an almost guaranteed loss of yards if he chucks that short toss to the scatback. Instead, he 'sees' the LB and looks for a better option, finding it in the TE (even though an argument can be made for the WR yelling, 'I'm Open!').
I don't disagree that QB vision has always been a questionable part of the game. Seen FAR too many missed open looks and FAR too many throws into a sea of defenders to think QB's are really this blind/stupid. I can understand the occasional mistake... but it happens WAY too much to be called 'occasional'... more like "likely on any down". QB's... even low level ones... just ain't as stupid as they play in this game.
