a) I don't think anyone envies NY sports teams (I say this being from NYC). The Giants were lovable losers for the last 20 years, until they won last season. The Jets, come on, it's the Jets. The Knicks are a joke. The Yankees - yes, lots of hate. Mets - again, maybe some, but why? They suck! (I'm a fan). So that's 1/5. Not much hate.
b) Cowboys fans (including myself) really have no business talking trash until we see how the next month plays out. The two teams are pretty evenly matched right now (both in terms of their play lately and their 1-1 head-to-head). None of that matters though - just what happens on the football field. I hope they meet in the playoffs again - it should be fun.
