Could be, though I also think the DH who can't play a position barely exists anymore (unless he's an elite hitter). But however much Howard is deluding himself or limiting his options, a playoff team is actually gonna look at him for two weeks, and he won't be close to home like last time.
Can't imagine he'll actually need his glove, if he gets to Denver. Maybe for a double-switch. The Rockies are loaded at 1B.
