The Spartans beat the Wolverines 47-42 behind standouts Matt Humphrey, DJ Cooper and Brandon Spearman...
Simpson finished with 10 points, all on dunks, in his first game with the Wolverines. Point guard Keyon Smith added nine points, but it wasn't enough thanks to Humphrey's late-game heroics.
Humphrey, who scored eight points, had two crucial steals in the final minute that sealed the win.
"We are one of the best teams in the state," Humphrey said. "When Josh is here we are even better."
Cooper sprained his ankle with five minutes to play and did not return. But he was clearly the best player on the floor. He had 10 points, seven assists and four steals. The rising junior point guard hasn't made much of an impact on the national recruiting scene yet, but that will change.
Spearman, a rising sophomore reminiscent of Jerel McNeal, stepped up in Cooper's absence. He scored six of his eight points in the last four minutes.
Hales was without big man Josh Crittle (visiting family in Atlanta).
Humphrey hinted that his college decision may come sooner then August, which was the timeline he mentioned last week.
