But according to Laettner, Allen must learn from his elders -- Laettner was famous for the turnaround buzzer-beater in 1992 that beat Kentucky and sent Duke to the Final Four but infamous for stomping on the chest of the Wildcats' Aminu Timberlake minutes earlier.
"He's got to see that, 'Hey, Laettner made a mistake, and it's haunted him for 25 years, and I would never make that mistake, so I'll never do that,'" Laettner said in an interview with USA Today.
Allen is a 6-foot-5 guard with a certain swagger as a respected perimeter shooter. Laettner was an inch short of 7 feet but never short on bluster in his four seasons with the Blue Devils, with whom he won national titles in 1991 and '92.
With Duke entering a Sweet 16 showdown with Oregon Ducks on Thursday, Laettner said he hoped Allen, who twice tripped opponents last month, learns from what Laettner went through; Laettner went on to forge a 13-year career in the NBA.
"I was like, 'Ah, poor Grayson. I hope they don't do to him what they did to me,'" Laettner told USA Today. "It's not nice, it's not fun and it's a little unfair."
Late last month, Allen, a sophomore guard, stuck his left leg out and tripped Florida State's Xavier Rathan-Mayes with 3.4 seconds left in Duke's 15-point romp. That incident happened after Rathan-Mayes appeared to grab the back of Allen's jersey in an attempt to fling himself down the court.
Allen has said he didn't think the issue would linger.
The ACC reprimanded Allen after the FSU incident but opted not to suspend him.
"It's just being smart," he later said. "I've had to be smart all season. Obviously I made a mistake, and I messed up."
