I don’t think in-season tournament winner needs any incentives like that. If cards lay right, it could be good thing on its own.
Imagine we will have final in Vegas between Denver and Philadelphia this season. Odd-wise it is hard for both teams to meet in play-offs. But this final is a great opportunity to see Jokic vs Embiid in the game, which actually matters a little bit. Not a regular season game, not NBA finals either, but I expect still this game, if it will happen, have pretty big hype.
Think about how we never had Kobe vs Lebron playoff series. One game, obviously, is not a playoff series, but it is still better than regular season game, when one team is on the road trip, tired, or on b2b.
If we will have Jokic vs Embiid, Jokic vs Giannis, Doncic vs Tatum, Giannis etc, basically some match-up of players/teams, that we are unlikely to see otherwise in Vegas, I would consider this tournament a success.
Imagine the team with Haliburton, Adebayo, Mikal Bridges and Laurik Markannen. Everyone esenare role players that fit. Will Haliburton be the best player? I would say you can argue it.
Can this team win championship? Possible
