CENTENNIAL, Colo. -- It apparently takes quite a bit to impress Nathan MacKinnon, at least when discussing his own game.
The 18-year-old Colorado Avalanche rookie had two assists and centered a line that was dangerous throughout his team's 6-1 opening-night win Wednesday against the Anaheim Ducks, yet he stayed on the ice to work on his game for about 40 minutes after practice ended Thursday.
"There's some things I have to do better," said MacKinnon, the first player selected in the 2013 NHL Draft.
MacKinnon set up Jamie McGinn for two goals, had one shot on goal and was plus-1 in 15:31 of ice time in his NHL debut. He showed plenty of speed and playmaking ability, and he held his own in a physical battle with Ducks defenseman Ben Lovejoy.
