I see little about Markstrom that makes him more appealing than Grubauer. He's a 30 year old who will be fishing for a big contract. He's never started over 60 games in his career.
He also has quite the injury history himself. In 2017 he had season-ending knee surgery. Before the break this year, in February, he took another knee injury that held him out for 6 weeks (with another surgery). In the playoffs this year, the reason Demko started is because Markstrom had a groin injury. He's not exactly proven himself to be more durable than Grubauer.
The reality of it all is, we're not likely to get a guy who actually has significant appeal over Gruby. Most goalies in the league have some sort of injury history that could ramp up at any moment really. And, there's just not that many guys in the league who are legitimately better then Grubs.
Grubs last 3 years in the league now(Last one with Washington + Two with us)... His numbers overall are towards the top in the league.
The stats are as follows over the last 3 years(For all goalies with at least 100 starts):
- 8th in sv% at .918
- 7th for GAA at 2.54
- 10th, for % of games started with a 90% or better sv%(62.9%)
Out of 36 goalies who meet the 100 games criteria, so basically the 36 goalies who have spent considerable time as the go to starter goalie in the last 3 years. And Gruby ranks Top 10 in all categories that IMO most accurately grade a goalies performance and not the teams performance(GAA is kind of a mix of both).
He's a good goalie. He really is. I get the concerns with injuries, but before this year injuries weren't a concern with him and there's a reasonable possibility they wont continue to be going forward either.
EDIT: Just to add a bit more context... His playoff numbers are pretty much the same thing.
Over the last 3 years, for goalies in the league with at least 10 playoff games, Gruby ranks 9th in sv% at .917(Tied with Vasilievsky, Hellebyuck, and Holtby btw), 8th for GAA at 2.36, and he's 11th for % of games above .900 at 61.9%.
Those stats was out of 21 Goalies who have been the starter in the playoffs for at least 1 run in the last 3 years.
So again, roughly average numbers(Slightly above) in the playoffs as well, and very similar numbers to some of the widely considered elite goalies in the league right now(Vasi and Helly are two of the best in the business at the moment).
