Brown scored 10 points in the second half as the Spartans pulled away from the Lakers but chastised the team for not finishing the game.
"We've got to improve on the bad things and keep working on the good things," said Brown. "But I don't think we rebounded well. And we have to learn to keep playing."
Michigan State established a 25-point lead at one point before allowing the Lakers to get back into the game. MSU was outrebounded 36-33 a statistic not lost on MSU coach Tom Izzo.
"We went inside,[but] we just didn't get much production out of our inside guys," lamented Izzo. "We played pretty well, defensively. We didn't rebound great in the first half. In the second half, we didn't play very well. We didn't rebound the ball very well and we didn't shoot the ball very well. We just kind of played like a team that had a 25-point lead. To Grand Valley's credit, they didn't play that way. It's hard to keep that going."
MSU's Paul Davis went just 1-for-5 from the field. The Spartans next take on the Northern Michigan Huskies in an exhibition game on Sunday.
