first off, as a bama fan i love gmac. but as a media personality, he's at bit over the top on a lot of his takes. seems he's trying to be a bit of a contrarian oftentimes.
as for the play, you play until the whistle. arky had a dude standing right in front of him, literally asking why hasn't the whistle blown (was in artcile i read yesterday). at minimum, grab him and make the refs blow whistles again.
is it kinda bush league? yeah, it is. but so is wr pick plays, and linemen 3 yd downfield, and fake spikes, etc. they're cheap plays to take advantage of people not paying attention (be it players, refs, or coaches), but they're part of the game. gotta have your head in the game.
