You may get your wish as this year looks to be the most horrendous yet. This could be the nail in the coffin. There used to be a time though when real celebs like Timberlake, Reggie Bush, Nelly, Ice Cube, Jamie Foxx, Tim McGraw, Bill Belamy, Frankie Muniz, Chris Tucker, Wilmer Valderrama, etc. would come out and you'd have celeb coaches/owners like Diddy, Gabrielle Union, Queen Latifah, Ashton Kutcher, etc.
They couldn't ball, but at least they would go out, have some fun, not take themselves too seriously, and provide some great moments (JT crossover, Nelly spin-cycle move, TO's throwdowns) and more often than not, some unintentional comedy.
Over time they added WNBA players, more ex-NBA players, and Globetrotters. Basically people who do this for a living but aren't as good as NBA players. That's when it got bad, IMO.
