I'm not sure how it relates to McDaniels, but I do tend to feel that Mac thrives when he's given the green light to play aggressively. He seems to have a bit of a gunslinger vibe to him, mentally and in terms of how he plays. Folks mention Brady, Brees, and Manning, and I definitely see elements of those guys in Mac ... you know who else I see in Mac? Tony Romo (in a wholly positive sense). The slight c-cks of the ball on his pump fakes, eye movement, mannerisms. It's not 1:1, but he has some elements of Romo in him. At any rate, Mac seems to really play well when there's nothing to lose and they start pushing the ball downfield. Incorporating that into the offense while still trying to remain efficient seems like a good idea.
To quote Bledsoe, "f*ck it, go out there and sling it".
