Tim,
While I think your last point is valid, the facts remain: The LIV Tour is mostly has beens and never was kind of guys, so its not hard to infer in its current state, that's its not exactly a good move if you care about your game and routinely playing again the best competition to stay sharp.
But sure if its about the Benjamins, putting your career on cruise control, and cashing easy checks then I can't argue against that, (morality questions aside). And its not like they are the only pro athletes who do this. There are certainly guys in football, baseball, basketball who cash in on a long term contract and ride it out....but there are also some who take a lot less than market value to win a championship like the GOAT of the NBA.
