Link That would be cool. Althought having played some soccer and living in Brazil I don't really think it's all that likely he can pull it off, it's harder to do it with a basketball and I am not so sure how good are Rudy's soccer skills.
How about something like this? <object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/agenl3kuWsI&color1=0xb1b1b1&color2=0xcfcfcf&hl=en&feature=player_embedded&fs=1"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/agenl3kuWsI&color1=0xb1b1b1&color2=0xcfcfcf&hl=en&feature=player_embedded&fs=1" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object>
I wouldn't be surprised to see him do something like that. It isn't very difficult to do, for as hard as it looks. About five years ago I was a freshman at OSU and everyone on my intramural basketball team (except for me and the PG) could dunk. During pre-game warmups they all dunked. So I rolled the ball on the floor like a soccer ball and rainbow kicked it to myself for a layup. It was pretty slick. And totally doable.
