Idk, I'm not particularly concerned. Raanta has been fine this year when healthy. If we're talking about the playoffs, Andersen is a clear-cut #1 that will start every game unless he gets hurt, and in that case we go to Raanta, and only if he gets hurt do we even have an issue.
You know who's a perfectly serviceable #3? Alex Lyon, the guy we signed in the offseason to be our #3. We do not need Holtby or Fleury or whoever.
I don't feel like this is a place of need for us right now, and I'm not really sure where the concern is coming from. Lafontaine was an emergency add based on COVID protocol throughout the organization, and he probably was promised an NHL start in order to jump ship from Minnesota. Now he's back down, and we have the Andersen/Raanta duo that we've always had, unless I'm missing something.
