That's not mind games, it is working the refs...and it is absolutely a great move by Jackson. He just put the refs on guard, and they may now be looking for KG's physical play in the post, a bit more than they were before. Point Jackson.
A very very weak point, to the point that it's a lame point, and a such a negative point, so -1 for Jackson. What KG did was an obvious foul and was called as such in the game... so the refs aren't going to be on the lookout for KG's karate chops anymore than they were going to do so initially.
He could have pointed out to other physical plays that would've actually had some sort of impact with the refs, not this one.
I agree that it does not have a huge impact, but ultimately, I think it serves the purpose. KG's "chops" were a perfect example of a player being overly physical, and breaking the rules in order to intimidate his opponent. Jackson's argument is that he should not be allowed to break the rules to intimidate his opponent.
Personally, I thought the Karate chops should have been a technical, but that's just me.
Anyways, you can certainly argue that Jackson is conveniently ignoring the fact that his own player is notorious for the same type of thing that he is pointing out KG does...but of course he is not going to point that out, because this is not a question of morals or anything like that, it is a question of trying to get a slight edge in the game.
