OK, the ten teams I'd have a no-trade clause to:
I'm on the Red Sox:
1.) Yankees. If I was drafted in the Yankees system, I'd play for them. I know it's a business, but I can't understand how any of these players can switch sides willingly (a Mark Bellhorn situation is different because he was released by Boston). Show a little passion. Besides, when was the last time the two teams traded anyway? Didn't it involve Don Baylor?
2.) and 3.) Marlins and Rays. For reasons Jim mentioned. Completely passionless fan bases.
4.) Dodgers. Team is in a mess right now.
5.) 6.) 7.) Astros, Rangers, Braves. For similar reasons Jim mentioned. I have no problem visiting the south, but I wouldn't want to live there. If I had my way, I'd live in New Hampshire or Vermont. Perhaps someday.
8.) 9.) Royals, Pirates; two going nowhere teams, and while I'm not an expert on their farm systems, I don't get the impression they have a future
10.) Seattle Mariners. The trains alone would drive me nuts, but this is a team that seems to fall apart no matter who they sign. No thanks.
Team I'd like to be traded to:
Baltimore: Yeah, call me crazy, but with Showalter, Matusz, Wieters, Markakis and Jones, I think they're a few pieces from being competitive. They also have a real history, it's not too far from where I live, and I think the fans would show up again if they could compete.
