The Dallas Stars two-headed goalie monster is doing about what should have been expected of them. They're giving the Stars average goaltending, and with as much talent as they have up front they don't really need much more than average goaltending to have a good team.
Recently there have been some complaints about how the goalie rotation has been handled, but anyone complaining is wasting a lot of energy on something that doesn't really matter. Antti Niemi has a save percentage lead on Kari Lehtonen of .005. We're talking five goals for every 1000 shots against.
