I think, if we add a DH, that should only be at most, like real baseball with a DH and without a DH for the two leagues. I'm sure a lot of owners planned on not having a DH, myself included. It wouldn't be fair to them if they had to all of a sudden take a DH when the signed up for it without.
Having Edgar Martinez, perhaps the greatest DH of all time, I of course am going to vote for my team being able to take advantage of him, but I do not think all 24 owners need to have a DH.
Perhaps everyone should vote whether or not to include a DH, and then, if the majority think we should have a DH, we can have volunteers to be in the DH league. Just a thought.
