Gotta agree with Saugus, no one is worse than Steigerwald and Errey. I almost always end up muting them at least halfway through a game they're calling.
They are hands down the worse, Steg is just god awful to listen to. Homer Joe isn't actually that bad when he is doing neutral games, I was surprised how tolerable he was during the playoffs last year when he was doing the west coast games.
I used to like Rosen better than most until I realize he says the same things every single game. Every announcer has their own buzz words but Rosen has like 5 phrases that are just repeated every minute.
