Absolutely. EuroLeague would charter the planes before the NBA could hang up the phone after making the invite. Most of those clubs average 8-9k attendance per game, and even the Final Four where 19yo Luka Doncic torched everyone barely got to 15k. NBA teams average 18k for the season and a ticket costs way, way more, to say nothing of the massive difference in TV money.
Maybe the single-elimination tournament could include some of them. Sure, the NBAs could always opt not to take it seriously, but how embarrassing would it be for them if they lost? Meanwhile, the Euro teams would each be playing their own personal super bowl if they got to take the court against an NBA team.
Imagined format:
64-team 6-round single-elim tournament with byes.
- NBA teams ranked top 2 in each conference at some cutoff date, plus the defending conf champs (or next highest-ranked finisher if overlapping) get byes to the R16 / R3. That's 6 teams covering 24 R1-level spots.
- NBA teams ranked 3-6 in each conference at a cutoff date, plus next highest-ranked finisher in the previous year's playoffs, get byes to the R32 / R2. That's 10 teams covering 20 R1-level spots.
- That leaves 14 NBA teams for 20 R1 spots.
- Fill the remaining 6 with EuroLeague teams, or a handful of them plus a few oddball entrants who could assemble a credible all-star team without including NBA players. Put a G-League All-Stars team up in there, you think they wouldn't be motivated to play the Wizards or Knicks? Put a College All-Stars team in there led by Coach K, let them go lose by 40 to their future coworkers.
- Play roughly 2 rounds a month on scheduled 3-day breaks in the NBA league season starting in, uh, January? Would give each team ~2 weeks to sell tickets to a game they'd just qualified for, but only a few teams would ever have to scramble because the bye-to-R2 teams know they're hosting an R2, and the bye-to-R3 teams know they're hosting an R3. Can put a R3 or R4 date right around the ASB.
- So you see a champion crowned maybe a week before the NCAAs start, and everyone can watch the semis and finals on, say, a Monday and Wednesday.
- Union agrees to the extra games, gets a ton of extra money thrown to the players, maybe agrees to extend the season by a few days on either end
How fucking fun would that be?
