I don't know about Compher being amazing defensively. He's a good 3rd line RW who consistently puts up 0.5ppg, but his possession metrics (corsi and fenwick) put him among the worst on the team (albeit a very good team with many good players). His xGA/60 stats on the PK are also terrible. He's not a natural fit at 3C as his north-south game is better suited on the wing, but with Donskoi, Kaut, O'Connor at RW Compher might just be the odd man out. It would also be more expedient to lose him than a Dman to Seattle, not least to move a contract out to create some capspace for Makar/Landeskog.
As for Grubauer, I disagree. Grubauer's stats this season put him among the better goalies in the league, and he'd be well worth $5m aav. It's basically the Lehner contract, give or take a year of term.
For reference below is a post on hfboards by a poster called Pierce Hawthorne which features some stats on Grubauer to give you an idea of the level of goaltender he is:
Honestly.... The more one dives in on the advanced goaltending numbers of Grubauer, the more I struggle to see how anybody could want to trade him from a performance stand point, and it would almost certainly be impossible to replace him with a better goalie. His numbers this year overall were pretty damn good, but especially at even strength the man was very close to being the best goalie in the league.
Just looking at his Natural Stat trick statistics. At 5 on 5 he ranked:
- 3rd in the league for sv%(Only Khudobin and Rask were higher then him)
- 4th in the leage for GAA(Khudobin, Rask, and Jake Allen were the 3 ahead of him)
- 6th in the league for HD sv%(Allen, Rask, Blackwood, Binnington, and Crawford were the 5 ahead of him)
- 4th in the league for Goals Saved above Average at 13.14(Khudobin, Rask, Hellebuyck ahead of him)
- 7th in the league for HD Goals Saved above Average at 7.32(Behind Crawford, Binnington, Blackwood, Rask, Allen, and Helly)
He was one of the top performing goalies across every stat including some advanced stats that dive further in on the quality of shots he faced instead of just all shots, as well as his performance relative to other goalies around the league. He, Rask and Khudobin were the 3 that clearly stood out as being rock solid in every stat across the board.
Francouz on the other hand simply wasn't nearly as good. Overall, we already know Frank had the better sv% then Gruby, but at even strength Grubs was the much better goalie. Frankie was pretty average or even below average at 5 on 5. He had a .925 sv% at 5 on 5 which ranked 17th in the league. 2.37 GAA which was 22nd. His GSAA was 5.03, which ranked 18th in the league, way behind Gruby's 13.14. Where Frank really struggled was with the High Danger shots. He actually had a negative GSAA here at -3.14 and a sv% of just .804% against those quality scoring attempts.
Where Grubauer's numbers really struggled and Frankies shined through was on the PK. Frank was basically Top 5 in all those same categories when on the PK, while Gruby was well down the list towards the middle or lower half of the pack. I'm not really sure why that's the case, and something to maybe look at and really work with Gruby on for next season however. Because at 5 on 5 there's almost nobody better then him last year of the leagues full time starters(Only Rask).
Long story short, Gruby was great last year and aside from the injuries we really should not be concerned about how he'll perform for us. He's a good goalie who puts up fantastic even strength numbers with a solid defense in front of him to limit the hard saves for him. If Joe is confident he'll be healthy and good to go again next season(And Joe is confident in that) then we really shouldn't be looking at another goalie, anybody we bring in is most likely going to perform worse then Grubs.
