You mean what you perceive to be an illegal pitch while watching from angles not available to the on field umpires and with replays at less than real time. Never offering excuses, just plain simple information. Can't force you to understand something you don't want to understand.
Those responsible for the mechanics, rules and proper application are in attendance. Have you seen anything change in the manner in which something is called since the beginning? If we do, then you know something different has happened or the umpires have been given new direction.
So when you watch a full game with someone like Barnhill in the circle, you cannot see a single IP? As to anything changing since the beginning, what does it matter how it was called in the past? The pitch is either legal or it is not. Umpire either do their job or they don't. End of story. It appears based on your comment regarding direction, that indeed umpires have been instructed to look the other way and not enforce the rules of the game. That said I would have much more respect for umpires if they at least showed some integrity and said "Yeah, it is illegal but I am not going to call it." But to throw out lame excuses about angles is pure BS. Umpires guess all game long on ball and strikes but when it comes to IP's it needs to be so obvious that they are forced to call it? If umpires truly can't see the numerous IP's in fornt of them they need to find another endeavor to pick up a few bucks on the weekend. If they see it and are simply not calling it, then we have an integrity issue and they are making a mockery of the game.
