Gabriel Landeskog has missed the last two seasons after recovering from a major knee operation and needed a cartilage transplant after the 2022 Stanley Cup, and he's been on the mend ever since. There's been zero clue as to his return, and it hasn't looked good in the past.
Landeskog, drafted 2nd overall by the Avalanche in 2011, has been one of the best players in franchise history since his arrival. Winning the Calder Trophy his rookie year (22G, 30A), he went on a tear; averaging 28 goals and 63 points per 82 games. He was a key part of Colorado's defense as well, often being called upon to kill penalties, and had no problems throwing his 6'1 frame around.
