Trailing by one point with nine minutes to play in the game, Drew Neitzel sparked a nine-point turnaround with a three-pointer and a jumper to put the Spartans up by eight points at the time and ahead for good.
The Spartans beat the Cougars despite 21 turnovers and being out rebounded on the offensive glass 16-7.
Tom Izzo was left fuming after the game due to his team's performance.
"I will put up with a lot of stuff, but the effort related things I'm not going to put up with any more. If that means we lose a game, then saddle up and get ready for the talk shows and the papers to write a lot of nasty things because we're going to lose a game," said Izzo.
Now looking at a much better opponent than Chicago State, the Belmont Bruins visit East Lansing hoping to catch the Spartans with their heads down.
Junior guard Justin Hare leads the team with 15.5 points per game and although he is the only Bruin scoring in double-figures, Belmont features a very balanced offensive attack that returns six of its top seven scorers from last year's team that went to the NCAA Tournament.
"This team does run but they are very efficient offensively," said Izzo. "They have two good post players that they rotate, they have three very good shooters which creates some problems on the perimeter. It definetly will be a game we're going to have to play better in than we played against Chicago state in to win."
In its last outingS, the Bruins trailed Illinois by only six points, only to fall 77-51 after a strong second half by the Illini.
Drew Neitzel has been the Spartans' leading scorer in nine of the team's twelve games this season and is also averaging nearly 21 points per game in the last eight games.
Isaiah Dahlman will get his second start of his career after scoring a career-high 11 points in his first collegiate start last game against Chicago State.
Adding to the fire, power forward Goran Suton has been suffering from the flu for the past week and saw limited action against Chicago State, only scoring seven points.
Suton had a full day of practice on Monday and should be close to healthy for Tuesday's contest, according to Izzo.
Facing a veteran Belmont team, the Spartans are going to have to pull together and show a much stronger effort for their Coach, possibly starting with holding on to the ball and cutting down on the turnovers.
ed note: According to the latest reports, Goran Suton is doubtful tonight due to flu-like symptoms
