Stars HC Peter DeBoer throws goalie Jake Oettinger under the bus after Game 5 loss

The key part of that answer comes at the very end.

"I didn't blame it all on Jake. But the reality is, if you go back to last year's playoffs he's lost six of seven games to Edmonton. We gave up two goals on two shots in an elimination game. It was partly to spark our team and wake them up, and partly and knowing the status quo had not been working. It's a pretty big sample size."

That is a heck of a quote from an NHL head coach just minutes after their team gets eliminated for the second year in a row in the Western Conference Final. 

Saying you're not blaming it all on the goalie, and then pointing out that the goalie wasn't doing enough to beat the team that eliminated you two years in a row is a rough look. Especially when DeBoer has had some problematic history with goalies. 

His team in Vegas reached a boiling point when he replaced Marc-Andre Fleury with Robin Lehner, resulting in Fleury's agent posting a photoshopped image of Fleury with a sword with DeBoer's name shoved through his back. 

And while Oettinger has struggled the past two series against Edmonton, it's still less than 14 total games, which is not a big sample size. And as long as we are talking about sample sizes, DeBoer has consistently hit a ceiling in the Conference Final series, losing six of them in his head-coaching career with three different teams (Sharks, Golden Knights, Stars) and four different starting goalies, as well as two Stanley Cup Finals (Devils, Sharks).

Maybe it's not the goalie that is holding DeBoer back. 

The Oilers were clearly the better team in this series, and they have a legitimate shot to win it all this season. You still want to go against them with your best goalie. DeBoer did not give the Stars the opportunity to do that in an elimination game.
