I havent watched much Mich football this year but others say their running game is not that great. I doubt the hawks get out of having 4 down linemen in the defensive line.
But if Mich subs into 4 or 5 wideouts or 4 wideouts with empty backfield and the running back split out as a wide receiver we need to have 5 if not 6 Dbacks in the game. Six dbacks means one lbkr probably the middle linebacker who might need to spy on their QB.
I think Niemann or Colbert have the speed to cover one wide receiver if we get caught in a mismatch.
