For the second prompt, I would easily change the rules of overtime because I think that as they stand they're pretty not great. So, the biggest change would be that the first overtime is a 5v5 sudden death overtime and that would last for 20 minutes, even during the regular season. Then, if there's no goals at that point, then from there we swap to a 3v3 overtime that only lasts five minutes. If that doesn't last, we pull the goalies and go back to 5v5 for 5 minutes. If there's no goals THEN, from THERE we go back to 3v3 but there's still no goalies. From there, if no one still scores for five minutes, we let the goalies go at it 1v1 first to 5 goals wins. This would surely not only be safe but would also be incredible for ratings and making sure that people felt engaged with the games. I think while not balanced, this would be electric and amazing
