No need to be condescending.
While an expiring contract has potential value, the value isn't very much compared to what it used to be. We've seen the value of expiring contracts plummet with the new CBA.
Compare that potential value to the savings on the buyout, the team will save money on the buyout players don't get the full dollar value, and add in his negative presence on and off the court and its not a crazy decision.
If they need a big man due to injury they can just bring in a d-league replacement.
Also suspending him without pay never happens essentially, teams do it with pay to avoid nasty union fights about it. Teams have almost always lost grievances over withholding pay.
