My suspicion for how the injuries remain intense, but never worthy of missing a game for is that the players are actually part of a secret project run by the Canadian government. Even the non-Canadian players and teams, yes. They’re part of the Department K branch. But this project, named Weapon H, is tasked with the explicit purpose of crafting the greatest hockey players known to man. Grafting the strongest metals to bones, altering their mindscape to only think about hockey even outside of the games, you name it they’ve done it. To address the injury question, naturally fast healers are researched so that the knowledge within can be applied to all of the players within the league. It’s also why our players have exquisite Leadership, Temperament, Professionalism, etc. Weapon H has crafted the players to peak performance, and that means that we can’t have any beef outside the game affecting the gameplay.
