There are several plans for realignment. After pushing for a plan that had as many as 15 teams changing leagues, Selig has backed off. Now, he is challenging owners to come up with a plan that pleases all 30 teams. Plus, there's the DH rule that has to be figured out. Getting a realignment plan will not be easy.
Teams have veto power.
He's checking with lawyers to see if that's legal. That's not a good sign if Selig's push for realignment gets down to legal fights. Baseball needs to slow down and let the attention be focused, for once, on the pennant races. Fans have been longing for that since before the strike, but Selig and the owners, in constant need of money, will not allow that. Baseball needs to celebrate and market the tradition of two separate leagues, making it the most unique of the four major sports.
