Just saw a report about a couple of safeties (Aubrey Pleasant, Shane Carter) that got suspended indefinitely from Wisconsin's team for unstated reasons. Carter was suspended for the Bowl game last year so this does not bode well for him.
Both are 5th year seniors and both started all games in 2007 with Carter earning Big-Ten honorable mention with 7 INTs that year. Pleasant only started 1 game last year and Carter started 7. The two starting safeties from last season are back for the Badgers but these guys were definitely in the mix. At the very least both were going to be important contributers this year. Pleasant was their nickleback last year.
It'll be interesting to see if they get reinstated but apparently there is "no chance of being reinstated before camp ends" according to the story. Theoretically our game is late enough that the Badgers should have time to fill those gaps up to a certain extent, but Wisco's D just took a significant hit.
