Supposedly the plan in the UK (not for the NHL, other sports) is to ban pubs from showing them, but play behind closed doors and dish out 'free' streaming to ticket holders, so they can watch at home even if they don't usually have access.

Seems the best overall to me. Combined with testing all players maybe.

Yeah, it would need to be combined with a (long overdue) closing of all bars.

Also large chunks of or entire teams might get quarantined if they are all practicing together.

And to avoid contact between players.
