Bottom line...The guy in the booth will have ALL THE ANGLES we have on T.V.
Even when the TV Crew see's the play, there's times they both see it different ways.
To me, the more important part of the Booth Umpire will be interpreting the rule without the confusion on the field. It will be a more logical, thought through process. Along with the ability to "LOOK" at all the angles.
Also, the Booth Umpire will be able to explain the RULE. Simple, it's all good!
Like roughing the QB, when a players pinky finger barely touches the QB...
