I support a return to Montreal for baseball and so does Scott Boras it seams. I think if they could get them put in the AL East that would be a bonus. You'd think MLB would be all for it, a Toronto/Montreal rivalry would be good for baseball, similar to the Redsox/Yankees.
It's been a while since the league was expanded. If they expanded to 32 teams it would eliminate the necessity for year round interleague play, but they'd still have the option of doing it if they so wanted to.
