Blake Griffin made another absurd alley-oop dunk against the Houston Rockets on Wednesday night and almost hit his head on the rim. The Los Angeles Clippers rookie grabbed a loose ball and started the fast break. He passed it to guard Randy Foye, called for the alley-oop, leaped up and slammed it in with one hand. "His head almost went in the hoop," the announcer said, amazed by the 21-year-old's skills. On Monday, Griffin threw down an unbelievable alley-oop dunk against the Minnesota Timberwolves.
