Is Mark Jackson the main reason the ESPN/ABC #1 crew is criticized? For 3 years, Breen and JVG were on their own and seemed to do well

I think back to 2012-2014, more specifically the 2013 Finals, when Breen and JVG were a 2 man booth and they seemed perfectly fine.

This current broadcast crew has been maligned at times, but how much of it has to do with Mr. HAND DOWN MAN DOWN?

Does he throw things off?

If you took out one of the other 2 guys with Breen, is it still a problem?

Or if it was Breen and Jackson as a 2 man booth?
