PMac's older brother used to be a huge Rafa fan. johnny Mac was very high on Rafa once.
Andre Agassi still loves Rafa while Brad Gilbert and PMAC have backed away in my estimation.
To me, PMac and Johnny Mac have positional power. They lay down the gauntlet for how the others are supposed to think. Years ago, Cliff Drysdale was praising Rafa effusively over the air and PMac got so nasty with him, it was uncomfortable. It was like PMac didn't even hold back. He forgot all of his professionalism. Cliff was stunned and then there was silence. As a listener it was horrible.
Afte that, Cliff didn't commentate for at least 6-9 months, but when he came back, he was sparing, it at all, his praise of Rafa. John is a master manipulator. He has everybody in his pocket and they do what he says too. Even Lindsey has backed down in her praise of Rafa. Agassi is the only one who isn't afraid of Johnny Mac. Andre says what he wants to say. The others? Not so much.
