Too many moronic dropped passes and too little creativity (where was the option today?) accounted for a tepid product on the field. It was only a matter of time before the Falcons took over, they're more disciplined and consistent. We have some sparks now and again, but with such poor blocking, there's no fuel to keep the machine chugging along; there will always be a play or two to break the momentum, and that's not Kyle's fault.
We should have run more often. But Morris benefits from defenders respecting RG3's ability to run, so once he left the game, they stacked the box and forced Cousins to beat them. That burned them badly ONE TIME and worked the rest of the time because they only needed to rush three or four to get to him, resulting in embarrassing INTs.
Basically, I'm not blaming Kyle for most of what went down in the second half. The first half was badly called, but also badly executed.
