How bad is John Sterling?

I know some Yankee fans who swear by the play-by-play of John Sterling. I try not to hold that against them as friends. In The Post today, Phil Mushnick pens a no-holds barred piece describing just how bad John Sterling really is. He writes that Sterling “may be the worst broadcaster in professional sports.” I doubt John and Phil will be dining together any time soon. (Hat tip to BBTF.)
