Original Picture Pages here. Analysis courtesy Brian, as usual. Now the slo-mo works but I'm back to non-lower-case lower case letters. Whatever.
Setup: Borges is setting up 'damned if you do, damned if you don't' situations. On the play prior to this one, Michigan sent Hemingway, Roundtree, and Grady to varying depths along the left sideline. The corner stepped up to take away Hemingway (running the middle depth of the three routes), but Roundtree beat the safety to the outside for a big gain. This play is designed to get one man open no matter which way the corner plays.
Wha'hoppon: Gallon is split left, Denard in the slot right, and Hemingway split right. Pre-snap, Junior motions in, and the defensive reaction reveals zone. On the snap, Gallon runs, well, I'm not sure - it might be a streak, or a fly, or a post, or a post-corner (#7). One safety steps up into a robber zone and the other forms a Cover-3 with the corners. Gallon's corner runs with him and the safety comes over. Hemingway runs what starts out as a deep in, I think (#6?), but continues it all the way across the field, getting free of the robber and being wide open in the spot vacated by the corner. The LBs are occupied by the threat of the end-around first, then a potential Denard wheel route second, which prevents them from dropping into the passing lane. Gardner finishes both fakes, has a quick lunch, tweets "no1 w/in 10yds of me lol wide open" and proceeds to throw into double coverage towards Gallon. Armpunt.
