My biggest concern with Ullmark is how many games he can start in a season. Career high is 49. Apart from that, he has 2 seasons at 40 and 41. That's just...not enough games as a starter. If we give him the kind of term and money he wants, he needs to be closer to 55-60 GS. Can he sustain his play with that kind of workload?
If he only starts 50 games next year, who plays the other 32? That's a significant amount of the schedule and it's a huge question mark.
Well, he did win a vezina when he played 49, so it doesn't appear as though he's a goalie that can't handle the workload,
So, Ullmark takes say 50 games, leaving 32 for presumably Korpisalo,
So, Lets make some assumptions:
We bring in a top 4 RHD, defensive structure is improved but still not perfect.
Ullmark gives us a .910 sv%, I think that's reasonably conservative,
Korpisalo plays the other 32 games, against lesser opposition, and improves to a .895 sv% (up from .890). That's due to a combination of better Defense and lesser opposition.
Now, using the same number of shots against, what would that mean?
As a team, last year we allowed 271 goals against a goalie, on 2442 shots against, a .888 sv%.
With the the above assumptions, we'd allow 232 goals, and have a .904 sv%. That's 39 fewer goals against,
Even if Ullmark only has a .900 sv% and Korpisalo repeats his .890 sv% we end up shaving off almost 20 goals.
