The Ohio State vs. Michigan football game ended in a brawl Saturday ... all because Michigan wanted to play conquering hero on OSU's field.
Here's the deal ... Michigan -- an unranked 6-5 team -- defeated their hated rival, ranked #2 in the country, in a dramatic 13-10 victory.
At the game's end, several Michigan players took a flag emblazoned with the yellow Michigan "M" and attempted to plant it in the center of the big crimson "O" at the 50-yard line .
