The San Jose Sharks and St. Louis Blues met on Tuesday in a battle of the unbeatens. The 5-0-0 Sharks arrived in St. Louis looking to validate their hot start to the 2013-14 season with a road win against the 4-0-0 Blues, an early-season Cup favorite.
The Sharks answered any and all questions surrounding their legitimacy with a 6-2 victory but were also left with a big question of their own.
An ugly incident less than five minutes into the game left the Sharks' Dan Boyle unconscious, face down on the ice, and the Sharks wondering about the health of their assistant captain.
The physical play continued later in the first period, and tempers once again teetered on the brink of eruption after a precarious hit by Brent Burns left the Blues' Brendan Morrow in a crumpled heap along the boards.
In a game that will be remembered for its violence, the Sharks finished the night 3-for-7 on the power play and extended their unbeaten streak to 6-0-0.
An update from Boyle, via David Pollack of the San Jose Mercury News, has since allowed the Sharks to breathe a collective sigh of relief, though his timetable for return to the team still remains in question.
With that most important question answered, let's look at four key takeaways from Tuesday night's game and one other nagging question.
