Not true at all. And folks that play him know he's not doing it intentionally. He's just a slow player because he does not want to miss, maybe a bit of "overanalyzing" as well. The clock forced him to shoot more quickly, and hopefully, down the road, he finds the right rhythm for himself since it does not appear he missed a beat with the clock on him.
He's a solid player that is still getting his "game right", which includes the mental side. And yes, we've exchanged a few texts over the last few days, and I told him that he needs to pick it up, and that it would be good for his game to be able to analyze the table more quickly, make your decision, get on your shot and pull the trigger. Less "mess" in your head, keep the negative stuff out which happens when over analyzing a shot.
