I think the Angels-White Sox would be a far better LCS then one involving the Yankees or Red Sox or both.
Both of the latter are almost exactly the same. They have awesome lineups, decent-to-good starters, and VERY shaky bullpens outside of the late innings. It would be a very boring series watching those two pound each other into submission interspersed with "commentary" from the Fox team.
The White Sox have a worse lineup then the Angels, but better starting pitching. I don't know much about thier bullpens, but I'll assume they are fairly equal. It would be a very interesting matchup, especially with the Black Sox Curse (
) angle for the Sox.
