Neither is the rest of the team, though. They've walked the line between being aggressive bullies and being a sloppy, penalty-ridden team for most of the playoffs so far, and in this series, they've crossed the line. Vegas is chewing up and spitting out the Panthers' penalty kill. Gudas is not himself (even before the big hit to the head) and that hasn't helped either. Finally, Tkachuk has seemingly come back to earth as well.
Not calling this yet, though. Panthers have a whole lot of "do not quit" in them. The wild card is, it's sometimes hard to "refind" your mojo, and Vegas is playing good, fundamental hockey. I hate them, but man is that fun to watch.
