It’s extremely hard to say that Williams was “much better” based on stats alone. Don’t forget that Fitz was our backup at the NHL level for like a week earlier this year. Obviously you’d like to see better stats out of him, but it was his first pro year and he was doing the ole’ Peoria Shuffle between St Louis, San Antonio, and Tulsa for a large portion of the year. He’s still learning how to be an adult, and while some guys have the preternatural ability to just glide through that, it takes some guys a bit longer to get used to living out of hotels, worrying about AHL vs ECHL salaries and accommodations, etc etc. Williams had the benefit of being through all of that already, and staying in one place for a vast majority of the season.
“Better” is just kind of subjective when it comes to goalies down the depth chart. I don’t think Fitzpatrick is the heir apparent by any means yet, but if you’ve got a spot to fill, and you want to do so internally, you put him there instead of Williams easily.
That said, if we’re looking for outside help, the following guys would be decent targets:
Fucale, McDonald, Appleby, McAdam, Halverson, or Wilcox.
