Whether it was sharking or not is irrelivant. The match is over and the results are history. In the end there's a winner and a loser. Those who look for reasons to discredit a victory will focus on any issue to support their cause. Unfortunately, many issues fall in the "Gray Area".
Would he have made the shot had Johnny kept his mouth shut???....Nobody knows, but one one thing is sure....Pool is a MENTAL game and if you cannot overcome a small distraction, there is a part of your game that is lacking. It's no different than having a flaw in your stroke. Distractions are a part of the game!
Do you think Johnny would have missed that shot had the shoe been on the other foot? Probably not.
Televised matches are only a small fraction of the games these top players compete. You can bet that when the camera is off, there are many subtle "head games" going on to gain an edge. It's simply a part of the game.
Johnny's response to the situation may have been completely subconscious and a result of behavior characteristic to the state of competition often apparent when the camera is off.
I've seen refs make bad calls and Johnny's opponent was approaching the shot in a way that lent itself to a foul. In addition, to stay out of the shooters line of sight, the ref was forced to stand a little too far away to really see if a foul occured given the fact the cue ball was almost touching the OB. I think Johnny may have been concerned that the ref was not "on the ball" per say and unwilling to let his fate be determined by an unattentive ref.
Hence, he simply confirmed the rule with the ref to be certain. To make sure the ref was paying extra close attention.
Was it sharking......depends on your perspective.
Where do we draw the line between acceptable and reasonable inquiries and those that are not.
If I bring the situation to the refs attention and lose the game...who do I blame? Myself. I lost on my own merrit.
If I say nothing and let a ref standing 5 ft away, make the call only to find out in rebroadcast that the ref missed the foul.....Who do I blame? Myself for not bringing it to the refs attention.
Since the blame for a loss falls upon my shoulders in either situation...I'd much rater lose on my own merrit than on a bad call.
