I fractured and dislocated my finger when the ball bounced off the gym wall and hit my hand awkwardly as I was reaching towards the ball, probably less force than Kyrie's hand slap but with worse consequences.... so yea freak accidents are freak accidents, the name says it all....
oh and J Kidd crashing his Escalade into a pole, lol reminds me of something, especially considering he's had marital problems as well
