Positives
Often known as a mercurial goalie, where the highs are very high but the lows are very low, Jonathan Quick turned in a perfectly average season in 2015. Among the 47 NHL goalies who played at least 1000 minutes 5v5, his .9275 5v5 SV% ranked 16th. Being in the middle of the pack among starting goalies is not too bad. You can work with that.
Is it safe to compare save percentage across teams like I just did? Probably. It's likely not true that every team lets in the exact same quality of shot on average, and thus some goalies will be a bit better or worse than their unadjusted 5v5 SV% indicates.
