The troubles continued for Michigan on Friday night, but the Wolverines rebounded for a weekend home-and-home split with Bowling Green Saturday night.
At home for the first game of the series, Michigan was ahead 2-1 in the third period, but allowed three goals in a span of 2:22 to Bowling Green in a 4-2 loss - UM's fifth straight.
Robbie Czarnik and Louie Caporusso scored in the loss and Bryan Hogan made 17 saves.
"We've got to stick together," said Michigan head coach Red Berenson. "We have to play smarter. There is no margin for error. You saw two mistakes by our defense in East Lansing cost us the game. We make a bad decision on the penalty kill and our penalty killers can't kill it. There is no margin for error right now."
The Wolverines headed down to Toledo Saturday night and came away with three goals in the first period on their way to a 4-1 win.
Carl Hagelin, Brian Lebler, A.J. Treais and Chris Brown scored to back Hogan's 11-save outing.
"You could hear the guys in the locker room after the game - we were all excited," Hagelin said. "But we know there's another week coming up against two great teams. We can't think too much about this game, but this is obviously great for our confidence to get going and have a good week of practice. We know that we can score four goals in a game and that's important."
