Doughty is a tank. Since 2014-15, the 31-year-old has been atop the league in average ice time while also playing in the third-most contests during that span, behind only Keith Yandle and Brent Burns. With over 1,000 blocked shots and almost 2,000 hits thrown in his career, his longevity is no small feat. 

Does Ovechkin ever get tired? In 16 NHL seasons, the perennial Maurice "Rocket" Richard Trophy threat has missed only 42 games, and just 24 of those absences were due to injury. The 36-year-old has thrown almost 3,000 hits while scoring at a 1.1 point-per-game pace. He doesn't have an off button.

Hellebuyck makes being one of the league's busiest goaltenders look easy. Over the past three seasons, he's led the league in shots faced (an average of 1,727 a year) while being in the top three in games played. The 28-year-old earned the Vezina Trophy in 2020.  

Few have stood the test of time in the modern NHL quite like Yandle. The 35-year-old defenseman owns the second-longest ironman streak of all time and looks primed to keep the train rolling as an important piece of the Flyers' revamped blue line this season.
