(EMLOS == End Man on the Line of Scrimmage, in this case Jake Ryan).
The ability to make my lower case letters actually be lower case continues to elude me.
Setup: EMU is on its second drive of the day. They have a counter bootleg called; Michigan will blitz Jake Ryan off the right side.
Wha'hoppon: Ryan reads the pulling OL coming at him and turns up the line to face him instead of blasting straight upfield (vice Brennen Beyer in the WMU game, captured in http://mgoblog.com/diaries/moving-picture-pages-how-not-defend-power-part-i), stepping inside the OL to clog the lane for the runner... who doesn't have the ball. This forces him to disengage the OL to the inside instead of to the outside, allowing the QB to roll out without having Ryan in his face the moment he turns around. One of the three receivers crossing right-to-left finds the seam behind the LBs and Gillett throws an on-target pass for an 18-yard gain.
The counter play-action froze the other linebackers long enough that they couldn't drop to the depth necessary to take away all the passing lanes. Ironically, if Ryan had blitzed on this play the same way Beyer blitzed in the aforementioned play (straight up the field at maximum afterburners), he would most likely have beaten the pulling lineman through the spot and dined on Gillett's soul, or at least forced an off-balance throw.
