Jim Harbaugh is pissed at Michigan State head coach Mark Dantonio.
Before the game, a situation arose where there was a small handful of Michigan players on the Spartan field warming up.
Michigan State players proceeded to take the field and make a human chain, walking right into the path of Michigan players.
Already some pushing, shoving and yelling. Michigan players didn't get out of the way for MSU walk. Devin Bush screaming in Spartans' faces as they run back to locker room after this. Bush in yellow. pic.twitter.com/Us9GWyVQch

After that transpired, Devin Bush proceeded to mess up the Spartan logo at midfield.
