Michigan won. They deserved to win.
The play took 8.39 seconds.
In college football, the 10ths are not shown. But in order for a second to drop, all 10ths have to be used. Until that point, the second will not decrease.
There was 0.61 seconds left at dead ball. 1 second should have remained for another 0.61 seconds before reaching 0.00.
