All the Braves legends played for somebody else. John Smoltz skipped town to play for the Red Sox and Cardinals when he wasn't offered a multi-year deal. Tom Glavine played for the rival Mets. Greg Maddux went back to the Cubs, then to the Dodgers and Padres and Dodgers again.
Hank Aaron played for the Milwaukee Brewers. Babe Ruth played for the Braves for his last season.
The fans love the teams more than the players.
Perhaps. Still, though, I think it would be understandable if fans of those teams were just a little bit upset at those veterans leaving. Would you expect Yankee fans to be happy if Jeter leaves?
(Which, by the way, I don't expect him to do, if for no other reason that no other team could possibly afford him. I also expect Mo Rivera to return as well, although in his case, I expect negotiations to be over much sooner, since there's none of the bad blood that seems to be cropping up with Jeter. And the rumor about the Rangers going after Pettitte is false, by the way.)
