Oats, 44, replaces Avery Johnson, who parted ways with the Crimson Tide earlier this week after four seasons in Tuscaloosa.
“We are thrilled to welcome Nate and Crystal Oats and their three daughters to The University of Alabama,” athletic director Greg Byrne said. “I have been watching Coach Oats for the last few years as he has led the University at Buffalo to unprecedented heights. His commitment to developing the student-athlete both on and off the court was what really stuck out. As we spoke to some of the best college and pro basketball minds in the country, his name came up time and time again. Coach Oats will hit the ground running starting tonight, and we look forward to him having a long and successful career with the Alabama Crimson Tide.”
