Mike Krzyzewski may not be coaching the Duke hoops team anymore ... but the team is making sure he keeps at it -- with this new puppy!

The adorable moment happened during the Blue Devils' annual banquet and award ceremony at Cameron Indoor Stadium on Thursday to celebrate their Final Four run.

Jon Scheyer -- Coach K's replacement as head coach -- was at the podium with the basketball team, Krzyzewski and his wife, Mickie, when JS introduced their "new family member."

"We can't repay you for what you done for all of us but we're gonna try," Scheyer said.
