Yeah, Nate definitely looked like he ran out of gas.
Bednar thinks because McDavid and Draisatl play similar (but less) minutes as Nate and Mikko, or Doughty, Jones, and Hughes play similar minutes as Cale, it's ok.
But again this isn't a smart way to look at this, for a smart guy like him.
These guys don't expel the amount of energy that Nate and Cale do. Nate's a thoroughbred and so is Cale. Cale also expels a tremendous amount of energy making sure he defends as hard as he plays offensively. The other defenseman don't. They save more energy at one end of the rink than he does.
Guys like McDavid, Draisaitl, Marner, Jones, Hughes, Josi, Heiskanen, Dahlin etc, they all play a much smoother skating style, and they still play less than the Avs guys.
Look at the style and the way the other guys skate who are in the top 10 in minutes. They'll have more gas in the tank because they don't pump their legs at a million miles an hour every shift, so they'll have less risk of fatigue over the course of a season, or multiple seasons.
