Am I the only one that’s going to point out that Andersen had those numbers while almost playing twice the amount of games Grubauer, is hold onto him until his contract is up, thank you very much

Grubauer played 49 games in total in 18/19, and 36 this season.
Andersen played 67 games in total in 18/19, and 52 this season.

The difference isn't dramatic, especially when you consider that Grubauer was injured for parts on this season. It's also worth noting that Grubauer has had Varlamov and Francouz as a goalie partner so there hasn't been a reason to lean more on him, unlike the situation in Toronto where the backup is significantly worse than Andersen.

Also, if you want to nitpick we can look at their respective playoff performances, where Grubauer has Andersen beaten in GAA and sv%, and also took his team beyond the first round - something Andersen didn't.

Grubauer (28):
18/19: 37GP, 2.64gaa, 0.917sv%
---- PO: 12GP, 2.29gaa, 0.925sv%
19/20: 36GP, 2.63gaa, 0.916sv%

Anderson (30):
18/19: 60GP, 2.77 gaa, 0.917 sv%
---- PO: 7 GP, 2.75gaa, 0.922 sv%
19/20: 52 GP, 2.85 gaa, 0.909 sv%

That all said, I think Andersen is probably the slightly better goalie which is why I wouldn't mind trading for him if it's necessary to save Toronto some dollars to enable the Nylander trade to happen. Not a big issue though, I'd gladly just leave Grubauer out of the trade too if it can work that way.
