A lot of times these bench-checks (or whatever you want to call them) happen very quickly. Not this one. Eriksson's journey to the bench was a gradual one, as he just rolled along the top of the boards before his momentum stopped, leaving his legs just dangling in the air. If Jay Bouwmeester hadn't helped right him, it's safe to assume Eriksson would have just balanced there for another few moments. Perhaps even the entire game.
Eriksson couldn't help but smile afterward. After all, we're all just having fun here, no?
