Of the thousands of crowd-pleasing dunks in tradition-rich Allen Fieldhouse over the years, just one shattered the backboard.
Powerful power forward Alonzo Jamison brought down the goal standard and splintered the glass during a Late Night With Roy Williams layup drill in mid-October, 1988.
"I think about it every day when I see the scar on the top of my head," said Jamison, a 6-foot-7, 225-pounder from Santa Ana, Calif., now the boys junior varsity basketball coach at Mill Valley High.
"We were in the layup line. I remember dunking the ball and my seat being on the ground thinking something had gone wrong. Obviously it's one of my favorite moments in the fieldhouse."
The slam seemed to thrill everybody except Williams and teammate Mark Randall.
"Mark Randall was right behind me in line. He said all he needed was one more dunk and his dunk would have shattered it," said Jamison, he and Randall figuring it was about time for that goal to fall.
"I was in the right spot at the right time."
Williams was in no mood to applaud the vicious dunk, considering one of his prize recruits - Jamison would sit out that season for academic reasons after transferring from junior college - was dazed by the rim and glass.
"He was more concerned with the player," Jamison said. "He was pretty worried."
Jamison was OK.
"I didn't need any stitches," he said. "I cut my head and maybe knocked some sense into me."
Jamison is not one of those basketball purists who believe the dunk should be ruled illegal in an attempt to stress fundamentals again.
"People watch basketball for exciting highlights," Jamison said. "Basketball is on a low with everything going on with the Olympic team (losing). Maybe the (U.S. national) team in two years will be better, but take away the dunk and all the attention will go out the window."
