They already have for two postseasons, excluding the Dallas series...which still had an .810 turd from Stu in it, but he did play great in that series. However, even Akira Schmid played great against the Rangers and a better goalie in Shesterkin in 2022 and he still found his way to the minors the following season...
Other than that, Stu imploded in three out of six playoff rounds: Vegas, Vancouver, and Florida...in the .800s in the first three games, including an .826 in Game 3 where the Oil only lost by a single goal and McDavid had two assists. An .869 would've tied it. Sure, he played fine in the next three games, when the team's chances of winning a cup were reduced to a single digit thanks in part to his collapse.
LOL if you don't think Florida let their guard down after being up 3-0. Stu's career .894 playoff save percentage is just diarrhea icing on the shit cake.
