Very interesting. The one that jumps out to me is NO HOT = SACK. This touches on an issue I've been chewing on all year. I'm sure Warner is referring to a hot read for a completion but Mac also needs to know every time he takes a snap for a pass play where his emergency out is in the pattern - where he can chuck the ball at someone's feet or out of bounds over their head to kill a play without a sack or IG.
Of course, the patterns have to provide those outlets.
