I'd be more inclined to go with Miller. With the Penguins being such a good team and having a guy like Vokoun behind Fleury, I'm sure they will give a decent amount of games to Vokoun, taking away some value off of Fleury. Meanwhile the Sabres will be fighting for a playoff spot, and will need Miller in as many games as he can possibly play given them there best chance to win every single night.
