I gotta go with John Wall and McGee to win their respective contests being a homer to MD/DC. Though, I just read a rumor on Twitter that Blake Griffin may dunk over a car. That would be INSANE.
And the 3 point contest is hard for me. Have been a Celtics fan my whole life, and Paul Pierce is my favorite NBA player, but Ray Allen is beast. Should be a fun competition, and I hope it comes down to them.
