In the past, Michigan painted commemorative-wins logos at the opposite 25 yard lines. This year, Michigan will be the first school in college football history to achieve 900 wins. With that stupid B1G logo on the field this year that practically eliminates any idea of putting "900" on the field unless they place them on the opposite corners, which then would make the field look even uglier.
But then again, it may not even occur during a home game. If we win out the first five games, it will occur at Purdue. If we lose one, the opportunity would be the Illinois game.
EDIT: The numbers displayed on the field in the past were, indeed, about games played. NOT wins. I'm not for throwing around inaccuracies on here. It was an honest mistake. Big. But honest. Thanks for the correction.
