No, of course not. Doumit isn't hanging on his back while he's hitting - it's not the dicussion at all. What you are arguing, however, is that his lack of success excuses playing Doumit at DH over him. Whereas you would've never accepted such a suggestion about Plouffe. Nor should any such suggestion be accepted when you have an aging vet who is neither contributing offense nor potential trade value and a young player is losing at-bats. While Doumit is playing catcher, you're correct - he's not blocking him. When he's playing DH, he's most certainly blocking him. And if you'e advocating to continue to block him for the rest of Doumit's contract, you might as well be writing Parmelee off. It's a distinction without a difference.
