It seems to me a lot that no matter who the announcer (besides Simms of late), there's always some anti-Pats bias. Which leads me to believe that the problem resides with me, as someone who despises the media and likes the Pats "us against the world" attitude. So I doubt that Enberg dislikes the Pats in any real fashion.
You're not crazy. My little sister-in-law ("little"...she's almost 23 now...man, I'm getting old ) who knows next-to-nothing about football watched a bunch of games this year. She asked me, "Um, do the announcers hate the Patriots or something? They're always saying something negative about them or praising the other team."
