No because the best duo currenly IMO is Joe Morgan and Jon Miller, and they're not anti-Yankee. Fox broadcasters have for a long time just always been anti-Yankee. I don't find ESPN to be that way.
I'll agree that FOX is biased, and that Murdoch has not have much love for the Yankees. I haven't noticed it with McCarver.
Miller and Morgan do an outstanding job on ESPN, which is certainly not anti-Yankee. ESPN generally, however, is the poster-child network of the prevalent East coast bias in sports, particularly baseball.
