Possibly as a subtle deterrent to trash talking ???? Lol No seriously though I do no condone these antics at all but I have seen this used as a shark move. Sounds a little crazy if uve never seen it but even something as small as not moving for like 5 seconds after balls are racked and ready to go can totally throw off shooter's concentration enough to mess up his run, his break, and if Po's enough his whole game. Believe me I cant tell you how many times I've seen this happen and its immediately followed by a scratch or poor break and as I said depending how mad someone gets cam put them on tilt and effects up to the whole rest of set / match. Also I agree with all the earlier posts that main reason is just about always ensuring the racket def had the needed time to get out of the way of the break. What are yalls thoughts on my theory on the shark move aspect?
