I don't think it has anything to do with 3's. It has more to do:
1. Making the game fake with all the lights, colors, & a floor that does not look like a basketball floor..seems like a circus & has lost the feeling of a basketball game.
2. No one plays hard until the 4th quarter & the playoffs. Shorten the freaking season.
3. Quit paying guys $300,000,000 contracts. These guys think they're kings.
4. Quit raising ticket prices & making games pay per view. Inflation is real & people ain't doing that crap.
Why in the world they think it has to do with 3's is beyond me & is probably why it's dying. They're discernment meter is broken. It's basketball not football.
