Looking at the "advance stats" way back in the mid-season, Anderson was facing some of the most high quality scoring chances against in the league.
I mean, he still wasn't good at all, but it was interesting.
So, at 16 games into the season, here's where Ottawa was in terms of SCA/60, HDCA/60 and Sv% all at 5v5
SCA/60: 24.47/60, ranked 5th lowest in the league
HDCA/60: 9.01/60, ranked 3rd lowest in the league
CA/60: 59.95/60, ranked 27th lowest in the league.
SV%: 90.68%, 3rd worst in the league.
In the remaining 66 games, here's how we fared,
SCA/60: 29.12/60, ranked 27th lowest in the league
HDCA/60: 11.37/60, ranked 21st lowest in the league
CA/60: 62.56/60, ranked 29th lowest in the league.
SV%: 90.85%, 2nd worst in the league.
He was bad when we were playing alright (we still had our issues even though on the aggregate we kept quality chances down) and he was bad when we were terrible. The quality of chances against didn't have all that big of an impact on the teams sv% numbers.
