Mrazek basically = Campbell.
It makes us more consistent over a long period with less difference between starter/backup - which is great for the regular season.
But playoffs are about elevating play in individual games and moments.
And you can only put one of them in net in any given game (obviously). Which makes this something of a sideways move if you are considering post-season aspirations.
Like it or not, Campbell had 3 tries to close out the series and failed to hit league median (.917) sv% in any of those games, losing all three.
He also had a sub .600 high danger sv% in the playoffs (Price was .800 vs Toronto).
If you think he had no role to play in the goals allowed i recommend re-watching the tape now that it's been awhile and emotions have cooled somewhat.
I don't actually think the game 7 gallagher shot was the issue, overall Jack was incredible on low danger chances such as that and i don't think that goal is something an opponent can replicate.
I am always more concerned with goals that expose technical flaws as they are more likely to occur again with some regularity.
For Jack, he struggled in finding loose pucks, struggled to keep his balance moving laterally resulting in lost nets and lost feet unnecessarily, went into RVH or VH in situations he should not have, and lacked decisiveness on bad angle attacks (similar to freddy).
These are fundamental technical issues that teams can attack, and Montreal did start to attack them.
That said, overall Campbell is a really good goaltender and some teams could win a cup with him in net, but I d0n't believe this team is good enough to do so.
Of course we are all allowed to have personal preference, and I definitely prefer goalies who have a more modern style and I know that a lot of fans are attracted to more old-school goalies.
