One of those two teams employed Pedro Martinez at one point, and seems like a fun bunch to watch play baseball.I wonder if it is. I don't think they'll top a list of absolute-favorites, but if push came to shove I think most here would back the Mets over the Yanks.
The other has directly removed us from postseason contention 3 times, two of which were in absolutely soul-crushing fashion, and is run and rooted-for by the biggest group of entitled assholes this side of Moscow (SoSHers excepted).
I don't think it'd be a close hypothetical here, like in a 3-way poll I think "I'll turn it off and sit around watching the paint dry" would come in 2nd. Unless you happened to marry a Yankees fan (which, I mean...), or the MonStars are playing a ballgame for the future of planet Earth, there's really not a lot of ways for a Red Sox fan to end up rooting for the Yankees.
edit: anyway, Tito and the long-suffering Cleveland fans, for me. A quick reward after changing their franchise nickname would be a nice karma carrot.
