I've dunked over Boykins with VC that's about it if that says anything to ya.
“I'm just honored to play for the Jazz and to play after John Stockton, to wear the same jersey he wore and be on the same floor he was on because he's one of the best players of all-time, one of the best point guards of all-time" Derron Williams - Utah Jazz
on a standard default keyboard, you can get a highflyer to dunk over a person by pressing c+s when they are close and the highflyer is close to the basket, its not quite the vince dunk but you do get the crotch over their head, lol
