Commander, I respectfully disagree. Your statement is arguable, and your analogy is not entirely sound for MD vs. DO. I think the best way to look at it, is by the individual player, not the team, although the team will most certainly have an influence.
While I agree that DO's might be at a slight disadvantage in the MD Match, with some Allopathic residency directors not even interested in DO's, I don't think it's to the extent that the quality between MD and DO schools differ to the point of being two different leagues, where one is lesser than the other, as you suggest. They are in fact, equivalent leagues in almost every respect. YMMV depending on school and individual characteristics.
Well, the truth is, I'm arguing from my perception, since I haven't yet started medical school, but your statement is still arguable.
