A goalie is bad because he has a bad defense in front of him... Rings a Bell TML fan?
Oh, you will wish for Korpisalo on your team after 5 games of Mrazek all right...
And Andersen will be stellar in Carolina!
Compare him to the goalies who have been on the same team.
The leafs goalies over the last while have generally been poor. Not the team making them look bad (though more recently better).
Korpisalo has had a below 0.900 save percentage in 3/6 of his seasons and below .907 in 4/6.
Meanwhile his partner has had a better save percentage and gaa than him for five straight seasons. Only in his rookie season was he better
Dude is simply bad.
Since he entered the league 6 years ago, 42 goalies have played 150+ games
He's tied for last in save percentage with a 0.905 (Elvis played two years and has a 0.920 and Bob has a 0.915 but would be higher with just his Columbus days)
He jumps to third worst by goals against average.
This isn't comparing to leafs goalies or anything else. He's just legitimately a bad goaltender
