Bret Bielema knew his University of Wisconsin football team had no shortage of motivation Saturday at Camp Randall Stadium. The UW coach was aware that his players wanted badly to send 18 Badgers seniors out the right way and that they wanted just as badly to gain a measure of revenge for a painful loss at Michigan last season. So Bielema might have played on those emotions a little bit when he sent the 21st-ranked Badgers back onto the field for the second half with a mere four-point lead over the Wolverines.
