Once you've picked your man, made your choice, it really is a good idea to have a plan B to fall back on.
Goalies are not Voodoo
The tools used to measure goalie performance are simply not as good as those used on skaters. While we now acknowledge that Goals Against Average tells very little about the goalie and more about the team, we still cling onto Save Percentage (SV%) as the only port in the storm. Even in its refined forms like the War on Ice Adjusted SV%, it has always suffered from two problems: the measure does not separate goalie skill from team skill well enough, and by the time you have enough data to make a reliable judgement on a goalie, you have just witnessed his peak years go by.
