Exactly. As someone else said during the draft, what do teams like the Cubs, Astros, Yankees, Dodgers do when they have a glut of the same positions? They find another spot for them. Honestly, some guys are talented and skilled enough to play other positions and pick up on them quick.
Edit: also, if we don't have a primary DH in a few years, that could be used to rotate and keep guys fresh on a game-by-game basis.
