Michigan blew a good portion of its 22-point halftime lead, but not all of it, in an 83-72 win at Wisconsin Sunday.  The Wolverines were shooting the lights out in the first half, hitting seven-of-nine 3-pointers on the way to a 44-22 margin.  Ethan Happ then led the Badgers’ charge from way behind, scoring 18 of his game-high 29 points in the second half.  The Badgers cut the deficit to eight points with about two-and-a-half minutes to go, but never got closer.  Wisconsin faces another ranked opponent at home Thursday when number-three Purdue shows up at the Kohl Center.  The Badgers will bring an 11-16 record into that game, 4-10 in conference play.
