Calliste was Detroit's third leading scorer a year ago, averaging 14.4 points per contest, while knocking home 73 three-point shots. At 6-foot-2, Calliste will act as an undersized scoring guard.
Calliste announced his intention to transfer from Detroit on Aug. 17, after graduating early.
He gave the following quote in an Associated Press story following his decision to leave the Titans.
"I needed to go, I was done it with,'' Calliste said in the story. "I gave four years and I gave all that I could give. It's time to move on. I've been there for so long. I've seen the good, the bad and the ugly. I know there's always going to be bad situations, but I just felt like it could have been a better situation, especially with the coaches that had to leave.''
Detroit reached the NIT last season, falling to Arizona State in the first round in Tempe. Calliste led the team in scoring in that contest, going for 19 points.
The extra scholarship that Calliste will fill immediately this winter, was only made available when Brazilian center Cristiano Felicio was ruled ineligible by the NCAA.
