ANN ARBOR, Mich. (AP) -- Michigan's season-opener proved to be a coming-out party for more than just its new head coach.
The Wolverines, on the strength of 23 points by DeShawn Sims and the heady play of freshmen back court tandem Kelvin Grady and Manny Harris, knocked off Radford 82-55.
The win marked a successful debut for coach John Beilein, who took over at Michigan (1-0) this season after compiling a 104-60 record in five seasons at West Virginia.
"The first game every year is tough," Beilein said. "Coaching the first game here was a very different experience for me, but one I will always remember."
Michigan jumped out to a 15-point halftime lead, thanks to 16 points from Sims and 10 from Zack Gibson. The Wolverines started the second half with a 12-4 run to put Radford away.
Sims, who easily eclipsed his previous all-time mark of 14 points, kept Radford (0-1) off-balance with a mix of perimeter jumpers and slashes to the basket.
"Some of the shots I took were kind of risky, but all that comes with learning," Sims said.
Sims added seven rebounds, including four on the offensive side. Sims played 27 minutes and made the first three-pointer of his collegiate career.
"He was terrific," Beilein said, "but I don't think that happens unless we have 16 assists and only eight turnovers. The guys who got him the ball deserve a lot of credit."
Michigan entered the game without their lone returning starter, point guard Jerret Smith. Beilein suspended Smith for the game on Friday for violating a team attendance policy. In his absence, Harris and Grady started in the back court. Harris finished with 13 points and four steals, while Grady added 11 points.
The Wolverines got a possible glimpse of things to come from the duo starting late in the first half. Grady grabbed a rebound and pushed the break up the floor, then found Harris underneath for an easy layup and a 14-point lead.
Grady and Harris continued to build Michigan's lead early in the second half. Following a Grady three-pointer, Harris took a steal the other way for an uncontested layup to give the Wolverines a commanding 20-point lead. Later, the two combined again on a fast-break dunk with Harris the finisher on Grady's bounce pass.
"We've done that since the first day we got on campus together," Harris said. "It's just chemistry."
Martell McDuffy led Radford with 13 points in what also was the debut of coach Brad Greenberg. The Highlanders committed 19 turnovers.
"I was hoping we would play a little bit better in terms of taking care of the basketball and getting back on defense," Greenberg said. "We helped them a little bit more than we would have liked and that's a little disappointing."
