Without getting into a full breakdown…. there were two (maybe three) significant offensive "gameplan" adjustments made for the UMich game.
Most probably know what they were.... but:
1) The increased utilization of Empty Backfield sets
2) The re-introduction of the "swing/flat" pass to the TB
(A third could be the specific "Outside Read Option" play involving Hamler.... that play run on the 3rd and 3 in the final minutes)
Empty Backfield... 7 Snaps:
1st and 10:
Swing Pass to TB in flat - Incomplete
2nd and 10: Straight Drop, pass complete to TE on out cut for 4 yards
3rd and 6: Straight Drop, pass complete on crossing route to slot receiver for -1 yard.
2nd and 6:
Swing Pass to TB in flat, complete for -2 yards
3rd and 8: Quarterback Draw for 10 yards
1st and 10: Straight Drop, pass complete to slot receiver on curl route for 4 yards
2nd and 8: Straight Drop. Heavy QB pressure, throw away
7 plays out of empty backfield.
6 passes (complete 5 of 6 for a TOTAL of 3 yards... w one heavily pressured "throwaway")
1 QB Draw (which worked well for a 10 yard pick up)
Swing Passes to TB... 5 Snaps:
In addition to the two listed above out of the empty backfield, ran 3 more:
2nd and 8: Incomplete
2nd and 9: Complete for 4 yards
1st and 10: Complete for -4 yards
Total from the TB swing passes:
5 plays... 3 completions.... TOTAL gain of -2 yards
The TB swing passes were the most head-scratching emphasis of a play for a particular defense that one could imagine.
Against a defense that plays VERY HEAVY man (like 75% of the time)… to try to throw those passes knowing (in all likelihood) that a defender was going to aggressively lock on and follow that TB out into the flat... is just.... IDK. Just stupid, I guess. (Even more so after throwing ZERO of them vs Iowa - who is about as heavy a ZONE defense as we will ever see)
IDK what THEY expected from those TB Swing Passes and Empty Backfields- against a defense like UMich..... but I don't think it was hard to anticipate that what they did get is exactly what one should have expected from them
(FWIW: The use of Hamler as a motion guy into the backfield could, I think lead to some interesting options.... though I would not hope to see it again in that "short yardage third down" type situation that we saw on Saturday - - - - even though it, of course, worked to gain the first down vs UMich)
