There is a wire service article out there saying Lebron had a benign growth removed from his mouth. Perhaps that was his foot?
Maybe I'm too old school, but I still beleive in courtesy and sportsmanship. I never liked players doing trash talking. When I was playing pick-up at the Wooden Center, I used to take extra pleasure from beating a trash talker. LeBron's explanation that he wasn't being a bad sport was wrong. It was the definition of poor sportsmanship.
