Out of the three “best actor” nominees, J.J. Barea probably has the easiest time selling his flops.
Barea is an average-sized man in a game full of giants, so unlike Kevin Martin and particularly Reggie Evans, he actually is going to get thrown around a bit. Funnily enough, it's the fact that he doesn't throw his body around that much that leads to all the fouls off flops.
The flop above is one of Barea's best and earned him his first warning from the NBA. After Sacramento Kings guard Jimmer Fredette makes slight contact with Barea's face, Barea acts like he's been hit with a wrecking ball.
Admittedly, no one reflexively throws their arms up in the air after getting brushed on the face, but it is the best way to get a ref's attention. So kudos for that, J.J.
Again, Barea smartly chooses not to dive onto the ground like so many other players would. There's a fine line between too much and too little when it comes to selling contact. Hitting the deck after some slight contact definitely would have erred on the side of too much.
It's hard to respect Barea's flopping ways, but even Kevin Durant would agree that you at least have to give him a nod for being a master of his craft.
