Red slides with what defense we're playing. If we're in an under alignment he's at the 5, if we go to a standard 4-3 he lines up wider and occasionally he even slides down to 3 in the nickel.
If you find youself trying pigeon hole a player into 1 gap assignment 100% of the time....well, just don't try. We're more dynamic than that.
Also, Babin is worthless as a run defender and near worthless as a pass rusher this season. Eagles suck and everyone knows it, but Babin is a one dimensional player who's one dimension has degraded to the point of decay.
