Sam's save percentage has dropped about 20 points in his recent play to .922 (which is still pretty good but not top-notch as it was), and giving up softies has crept into his game now in a way that wasn't there in the beginning of the season. Adam has played decently in recent weeks and getting some wins, but he's still not shutting anybody down, and his saves percentage (.856)and GAA (3.99) still reflect his awful play at the start of the year. The net-net is that DU's team goaltending has slipped from a strong .921 team average in early November to .907 average currently, which is just about average. Giving up 2.57 goals per game is okay when DU is scoring 3.3 GPG as they have, but as we know in the final months, defenses tighten and goaltending becomes much more critical.
I think Gwoz is hoping that one of these guys heats up into a playoff goalie, but it's the one area of DU's game that hasn't been stellar of late, and DU must get back to a .920 or .930 team saves percentage to get the GAA down and be a playoff contender...
