The thing is, it worked.
The Grizzlies were down four with 13.3 seconds left and needed a three, and they got one in practice when Chris Paul was called for a foul on Matt Barnes on the play above. Barnes comes off the screen and sells contact that is barely there. (For the record, the NBA determined this was the correct call, there was a foul, but that Barnes flopped in exaggerating the contact to make sure he got the call.)
The bottom line is it worked; Barnes got three free throws, and the Grizzlies stayed in the game (they eventually lost the free throw battle at the end). And for this flop he got a warning, which means if he flops again this season and is caught he could will a $5,000 fine — or 0.001 percent of his salary this season. That will teach him.
