I'm looking at the most accurate stat for evaluating a goaltender's performance, to evaluate a goaltender's performance. I also addressed your save percentage stat, and pointed out that he has a higher SV% in the playoffs than he does in the regular season. Evaluating Mrazek based on these small samples is pretty silly in the first place.
You're letting your perception be too impacted by the Mrazek performance you saw this year, which wasn't good. I'd like to look in a different direction for next year as well, but throughout his career, he's been a capable tandem goalie with a similar style to the one you were describing.
I haven't really seen anybody want to go with that next year.
