When looking at a goalies numbers you usually go by save % and wins,
a .920 3.00>.860 1.50
But the best way to scout a goalie is to let other goalies watch them play, completely different skill set from everyone on the ice and people who haven't played it usually just talk out their rear ends
I usually find Zeke is one of the biggest homers on HFBoards, but I don't think he's off-base here. Reimer has always impressed me more than Carey Price at the NHL level. He has the stats to back it up, too. A lot of people would argue that Reimer has also been backstopping a much worse team over his time period in the NHL too.
