Well, Kuemper has started 55 games ONCE in his career and that was a couple seasons ago with the Yotes. Next highest games started was LAST YEAR at 29 starts.
So, playing him at a 70 game rate when he's never gotten past 55 seems ridiculous. On top of the fact of him getting injured in the most recent season... just not smart player management.
Goalies usually have different types of injuries than skaters, I'd say. Their job seems to require a lot more muscle flexibility and mobility. So they should be treated differently based on that.
