You don't understand hockey if you think a goaltender's play can be evaluate strictly by wins, sv% and GAA.Stats over the past 3 seasons:
Goalie #1 GP: 170, Wins: 118, Sv%: .921, GAA: 2.53, SO: 17, Cap Hit: $9.5, Age: 26, Contract Ends: 32yr
Goalie #2 GP: 173, Wins: 78, Sv%: .910, GAA: 2.77, SO: 9, Cap Hit: $10.5, Age: 33, Contract Ends: 38yr
Do you want to re-evaluate or does your question still stand?
There's so much more to analyze than 3 statistics, that's why you're not a GM or a scout in the NHL.
Compare the rest of the team and it's style of play.
It's foolish to think all goalies face the same quality of shots, so much goes into play when evaluating the 30 shots a goalie faces each night.
