This idea comes from Provincial Rugby Union in New Zealand.

We have the Ranfurly Shield, a shield where if you beat the team who holds it, you get the shield.

I think this would be a super cool implementation into the NBA, it would add stakes to regular season games and make a win streak even more entertaining and exciting.

Its simple to implement and doesn’t require and new tournament to be created for it.

You could make it that it isn’t on the line during the playoffs, but only in the regular season and I think it would be super fun especially if your team is on a roll
