No question that Jarry's huge, unforgivable gaffe in Game 5 was the difference maker in the series, along with playing like crap just about every game. Win that game and it's very tough to see the Islanders come back and win the last two. Lose after thoroughly dominating the Islanders all through regulation and overtime in Game 5 and it was very tough to see the Penguins come back and of course they didn't. But that's hockey, the Penguins need to learn to play with less mistakes in the regular season and the playoffs, otherwise opportunistic teams like the Islanders this year (and Montreal last year, the #24 seed) will continue to beat them when it counts. Whether the likes of Malkin and Letang and others will ever absorb that now yearly lesson is unlikely. And sadly, Sidney Crosby has been a non-contributor the last three playoff years. His linemates of Guentzel and Rust are very good wings but are small and all it takes in the playoffs is to relentlessly pound them and they wilt, leaving Sid ineffective.
