In all seriousness, I voted Markstrom. I would definitely have Kuemper after him.
Gibson (as per usual) is really overrated here based on what he used to be. I'm pretty sure I'd say he's the most overrated goalie in the league right now. He's a .904% over the last 3 years and 142 games played. Since we are in a declining save percentage era, that's probably not horrific like it probably would have the 3 years before that (when Gibson was still elite) but it's also below average and not good.
Kuemper is actually underrated at this point and I think it's because of his poor performance in winning the cup where the Avalanche won very much in spite of him (and in spite of Francouz when he played) and his play.
But Kuemper was GREAT in the regular season and has certainly been in the top 7 or 8 (if not higher) of goalies in the league over the last 5 years.
I have said that I think he may have had his last great season in the league and he is an injury case and that might only push him towards not being good anymore, but outside of literally his last 13 games (since getting the eye injury) his play over the last combined 5 years has been very good. I'd bet his save percentage even including last playoffs is not much under .920% over the last 5 years. That's really good in a declining save percentage era.
I could argue Kuemper ahead of Markstrom, but he gets a few points taken off for being an injury case, as well as my own speculatory belief that his best days are nearing their end.
