The "charge" call on C.J. Fair has been talked to death, but I am going to raise it one more time.
This helpful vine that our own Jared E. Smith posted allows us see the "charge" call on Fair and the "block" call on Michael Gbinije back-to-back. There are a lot of similarities between the plays, which is what makes the entire thing most infuriating. Watch below:
Like I said, infuriating.
But there is one more thing about this that I didn't notice before (probably because I was screaming at the television) that if I had noticed would have made me scream even louder. Watch Tony Greene (the official who calls the charge). He is behind Fair and moving away from the play as it occurs. Now, of course, it is not uncommon for an official to be in motion or out of position when making a call. This is basketball and it is impossible to always be in position. However, from Greene's vantage point he cannot tell if Rodney Hood is holding his position against Fair or if, in the language of the new charge/block rule he, "move[s] into the path of" Fair after Fair "started his upward motion with the ball."
You can see very clearly that Hood does move toward Fair again after initially setting his position (unlike Gbinije) but that Greene cannot see Hood when it occurs because he is behind Fair. To make that call Greene has to assume that Hood does not move while he can't see him. And we all know what happens when you assume.
I have officiated sports off and on in my lifetime and I am by no means a professional. But one of the first things I learned was you should not call a foul if you cannot see the full play occur and if you think a foul did occur you should confer with the other officials before making it official.
