DENVER -- Teams that come to this town know all about Avalanche center Nathan MacKinnon, and how they have to devise a strategy to limit the damage he does.
They also realize that they must try to neutralize rookie defenseman Cale Makar, too, and that guys like Mikko Rantanen and Nazem Kadri can make their visit to Pepsi Center miserable.
But one thing the Penguins, who will face Colorado tonight at 9:08, insist won't concern them is the thin air here.
Denver-based teams take every opportunity to remind opponents that the city sits a mile above sea level -- witness the sign above, positioned over a doorway opposing players go through when entering Pepsi Center -- but Penguins players say the lower-than-usual oxygen level will not be a significant issue for them this evening.
