The Wisconsin Badgers got back to the .500 mark by beating Chicago State at home Wednesday night 82-70. The Badger record is 7-7.  Ethan Happ scored 18 points and had 12 rebounds in his team’s third straight win.  Khalil Iverson had 17 and freshman Brad Davison added 15, but had to leave the action twice with a shoulder problem.  Wisconsin didn’t blow out a Chicago State team which was losing for an 11th straight time.  The Badgers have one more non-conference opponent — U-Mass-Lowell Saturday — before returning to Big Ten play.
