I can live with either QB. Lucas was definitely much more likely to take his check down and keep it moving. Didn't really push the ball down the field, but I'm not sure the O-line blocks it up well enough to really push the ball down the field consistently. Graham showed surprising touch on his first TD pass bomb and he's got great speed and athleticism. Downside is, because he's so athletic, he was holding onto the ball too much instead of doing what Lucas was doing and taking his check downs and keeping it moving.
O-line was not good. D-line was not good against the run. But, it is a glorified touch football scrimmage. O-line definitely worries me more of the two.
