Alstons old vids remain eminently YouTubeable. Take a second to see what started it all, and then ask yourself whether he would have looked like something out of The Matrix had he not been playing against guys who might as well have pleaded guilty, such was their lack of defense.

This particular crew boasts such marvelous nicknames as Circus, ½ Man ½ Amazing, Spyda, Pharmacist, and Mr. 720, who used to go by Air Up There until he began incorporating two full spins into his dunks.

If the weather makes the decision for you, hit the American Airlines Arena (601 Biscayne Blvd, Miami) at 7:30 p.m. Tickets run from $10 to $75 on ticketmaster.com.
