I really do hate it when Babcock won't play Howard on back to back nights. Especially since he just had 6 days off! It's not like he's 39 years old, he's a kid, he can handle it. I know why they didn't play Conklin last night, it's out of respect for the opponent. As much as they won't admit it, it's just an unwritten rule that you don't put your scrub goalie in net against a s***ty team "just because".
In back to back games, teams put their best goalie out on the night with the best chance to win, and that is the first night, regardless of the opponent. That way you play the best team possible to give you the best chance of getting at least one win. If you try to backup against a weaker team the first night, you run a higher chance of going 0-2.
