While I'm not actually for Miller playing both games, I don't get why some people (not just you) are acting as though it's impossible. If it were, we'd see a lot more backups during the playoffs.
Remind me how many b2b games there are in the playoffs?
Of course it's not "impossible" to play Miller X games in a row, b2b, etc. It would just be stupid to do so, if our starter is 34 and we have a backup that we trust (and presumably we trust Lack, right?...a mere three months ago there were people who thought so highly of Lack that they didn't even want to sign Miller in the first place). Lack played 20 games in a row at the end of the season last year only because we didn't trust Markstrom at all. (It didn't turn out very well if I remember right.)
As someone else said, if you don't give Lack a game now, then when *do* you give him one? When Miller starts feeling the fatigue of playing every game and his performance starts to tail off? I have a better idea.... let's manage Miller's games and make sure that doesn't happen.
