The 41-year-old joined KJR in Seattle with Dave Mahler and Ian Furness on Wednesday and called Griffin's final dunk "weak."
"I'm a big Blake Griffin fan, but that dunk at the contest might've been the weakest dunk in the dunk contest that I've seen in a long time," Kemp said. "I love the choir and all that stuff was great, but you at least gotta jump over the car though right."
Kemp also said that he could jump over a car.
"I'm 41 years old and right now I could do it. Two Smart Cars," he said.
