"He brought the best out in players, and everyone liked him," Sims' coach at LSU, Dale Brown, said in a statement.

"He was a team player — didn’t get the credit maybe he deserved for the great run they had, but he was a wonderful person. He was never a flashy guy that needed stardom, but he was the base to our team."

Wayne’s son Wayde also played two seasons for the Tigers before he was fatally shot during an off-campus altercation on the eve of LSU’s first scheduled practice before the 2018-19 season.

Following their son’s death, Wayne Sims and wife Fay set up the Baton Rouge-based Wayde Sims Foundation.

"He and Fay worked tirelessly to keep Wayde’s memory alive," said McNeese State coach Will Wade, who was Wayde Sims’ coach at LSU. "I’ll never forget Wayne and Fay saying that God will find a way to save lives through Wayde’s death."

"I was very sad to hear of the passing of my good friend, Wayne Sims. He was a great teammate and even better person. If you knew Wayne, you could not help but be embraced by his extreme kindness. He will be missed by everyone who knew him."
