If this was ever to occur in our made up fictional land of the simulation hockey league you know damn right luffy would be at the top of his game and convert his house into his own personal work out glory home. Practicing to stay ahead of the long winter in doors and living it up like an instagram legend showing his filthy mittys and work out routine from home. Even if his home gym wasn't set up properly luffy would be curling his dog or children and benching his wife. Luffy takes this very seriously and will make sure that he social distances himself from all his loved ones and only his wife and kids get to see him till the pandemic is over. His hockey skills will never faulted and he'll be working the full 8 hrs or maybe even more to stay in shape and to practice his silky mitties.
