Re: Load Management - Is this going to be a thing in the NHL?
I don't know if it's going to translate much into skaters resting more than the occasional game here and there + before the playoffs. Where I do think this sentiment will become more established is with goaltenders, as you mentioned. The days of starters playing 65+ games are over, and I think most teams are probably comfortable with their #1 guy seeing about 50 starts over the course of a full 82-game regular season. Could we eventually see that split move closer to 50/50? Perhaps. But I highly doubt that the near future of NHL goaltending involves full-on committees or anything.
It is already starting to affect the fantasy game more and more. This past season, there were quite a few 1B type goalies that carried considerable value throughout the season: Greiss, Halak, Khudobin, and even Saros to name just a few. These guys who were typically only thought of as "handcuff" options in the past will start to become more valuable at the draft, and even in keeper consideration. Now is a good time to load up on goalies if you're in a keeper league, as I would imagine that with goalie load management becoming more commonplace, the truly elite starters will only increase in value. It's a sound investment.
