I'll start on offense ... on that penultimate drive that allowed IU to have the ball toward the end of the game. After picking up a 1st down with an Allen run off tackle, our 1st down play has Allen lined up behind Grunk in the shotgun, with Rappleyea(!) lined up next to Grunk as the FB. We also have another lineman in there ... in motion. OK, so you're going to smash it to that side. Motioning lineman will come through and clear a path and Rappleyea follows to get any leftovers coming from the side, etc. Got it. Except Rappleyea doesn't lead the way, after the motioning lineman comes through ... actually, the motioning lineman paused at the A gap for a moment, then loops around to the outside, outside of the blocking WR. Rappleyea gums up the play, cutting across Grunk and holding up the handoff ... making Allen pause and lose momentum ... and then Rappleyea goes outside of the motioning lineman. So either the motioning lineman and Rappleyea both messed up, or Allen messed up and that play was meant to go to the outside. Or AK outsmarted himself by trying to create a diversion no one bought, and therefore left his lineman outnumbered on an inside handoff.
2nd play .. Dinkins and Rappleyea lined up next to Grunk with Allen behind ... Dinkins goes to the left to reset on the line ... Rappleyea again (this time from the other side of Grunk) goes to the outside as a faux outlet ... everyone on the left blocks down, pushing the mass toward where Allen wants to go ... Allen has too many stutters, a lineman loses his block and fills the one small hole that was there ... virtually no gain.
Why not use the mass of bodies to help your cause, rather than use them as diversions? On that second play, have Rappleyea lead and he can pick up that IU defender who shed his block and made the play?
3rd down we move everyone and their mother to the left side of the line and then rollout right ... Grunk has been successful passing in a stable pocket. When his feet have to move, he panics. Regardless, this play is designed to be a quick dump to the TE, forcing him to win a 1 on 1 with a defender to make any yardage at all. He doesn't.
I'm definitely not one of those old school "I want 3 yards and a close of dust" guys ... but if you want to run the clock and grind out a first ... do it with a strength. Don't divert and go to a weakness that only is not a weakness if the defense is fooled. Yeah, I would have rather seen them be aggressive and throw for a first, but if you're going to try to run it, do it in a way where the odds are default on your side, not hoping you can trick someone.
