How did he do that?

Just look at Odom's PFs...

Is it because the game went into overtime? I didn't know that was possible...

There is a Laker's thread already, this should of put in there. But it was because there was a foul on him, but they changed it to someone else, so they must just not of changed it on that, so when he got his 6th in Overtime, it went up to 7.

more importantly
A) how'd he get 16 points?
B) how'd Kwame get 15-13
C) How'd walton get 12-7?

Ah, ok. I imagine it like this: Odom knocks down Melo hard and innocently points to Kwame, who gets the foul in the end. At least, he's good for something...
