When Danks is 100% healthy, he's an above average (damn good!) SP. Any staff in baseball would love to have him.
When VMart is 100% healthy, he is THE best DH in baseball. A dangerous hitter, that would be welcome on any team in baseball.
IMO, every day ballplayers are more valuable than SPs. The best SP can only help you win once every 5 games, whereas a position player, even a DH, can potentially help you win every game.
Does this make sense?
