It hasn't reached the point of Clippers fans covering their eyes and wincing whenever Blake Griffin hits the floor or lands out of bounds. At least the rookie hasn't crashed over the scorer's table at Staples Center this preseason, as he did about a year ago. But concern cranked up to, oh, say threat-level "blue" when Griffin landed hard on the court early in the fourth quarter Saturday. He appeared to do a quick inventory of body parts, left the game and had a quick word with team trainer Jasen Powell on the sideline. http://www.latimes.com/sports/la-sp-clippers-20101017,0,2532678.story
