It's on his right ring finger.
The Hall of Famer has been wearing his 2010 NCAA championship ring during the tournament, won the last time the Blue Devils were in the Final Four. He said Friday it wasn't something he does very often and was "a reminder to me and to our team of our ultimate goal."
His players have noticed heading into Monday night's final against Wisconsin.
"Every practice, every game when we huddle up, Coach has the ring in the center," freshman Justise Winslow said Sunday. "It's a constant reminder of what our goal is, serves as a great motivator every day to get better so one day we can reach our goal."
Assistant coach Jon Scheyer was the senior leading scorer on that '10 title winner and has a ring, too. He just didn't bring it out this week.
"I've never really worn it," Scheyer said. "It's in a safe place and I hardly ever take it out. ... I haven't brought it out as much as I should. Now that you mention it, I probably should do that once in a while."
