One thing I have noticed is that Smith is really good at bailing guys out. It's one thing to make the saves you should make, but it's another to make robberies after a guy coughd up the puck at the blue line leading to a breakaway. From a psychological perspective it gives guys confidence to be creative and focus on transition offense and varied breakouts. The results are not quite there yet as the Flames have been out of sync this year (and way too much Matt Bartkowski) but you can see it building. The three players who are most thriving right now are TJ brodie, Johnny Gaudreau, and Micheal Ferland.
The last time we had a goalie play like this was 2014-15 Jonas Hiller who made the Russell - Wideman pair look good. That was also the last time we won a playoff series. Hiller fell off the map the next year and was never the puck handler that Smith is, but he definitely had a knack for making timely, unlikely saves.
