I'm sure there will be a 20-21 season since there's enough TV money to make it worth their while. But I think playing in bubbles will be needed. Maybe they could play in 5 or 6 bubbles across Canada. Or better yet have 1 bubble per division based on where COVID is at its lowest.
I've proposed bubbles based on what region of North America each team is from
Eastern - All American teams in Eastern Conference except Columbus and Detroit
Central - All American teams in Central Time Zone plus Columbus and Detroit
Western - All American teams in Mountain and Pacific Time Zones
Canadian - All Canadian teams
All bubbles would be in Canada. It would be the first NHL season to take place entirely in Canada since 1923-24.
Bettman may have to realize that 82 games is not realistic.
