I have to disagree

The call seems fair and reasonable.  On the replay, it displayed that Barnes fouled Reggie.  Furthermore, Barne's left hand might touch the ball.  There is no definitive answer, but I think the Ref made a correct call under the circumstance. 

As matter of the fact, CP3 hit on RW's follow-through.  It was clearly displayed in the replay.  

Since complaining of the refs, how many times did Clippers foul on RW and KD in the paint?  There were a bunch of no-call.  I think the game officiating is acceptable and it is on par.  When JC hit a 3s and kicked his leg on Reggie, then he was rewarded on 4 point play.  Was that a bad call?  I can go on with a longer list.

The Clippers lost the game, because CP3 blew it.  There is nothing to do with officiating.  CP3 could have held the ball and taken a foul, but he didn't.  CP3 could have avoided to foul on RW on a 3s attemp, but he didn't.  CP3 could have not lost the ball, but he did.  CP3 could have fouled on 18k with 2s left, but he didn't.  A loss is a loss.  Be a man, and take it as a man.  Don't be a whinning baby.  I am not sure what Zen master and Pop did applies in this screnario.  The game was officiated fairly.  I haven't seen many bad calls and a huge discrepancy.  If so, it only shows it is a sour loser mentality.
