Why can't I do the Vinsanity "Clear the 7 footer"

A screenshot of that would be absolutly awesome.

I've dunked over Boykins with VC that's about it if that says anything to ya.

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
