So you are upset at the intent of the franchise? If the Kings traded for more 2nd round picks and sat Fox and Tyrese for the rest of the season, then lost 9 in a row... That's better than how they actually have lost 9 in a row?
Yes thats better. That way you dont risk injuries for Fox or Barnes, you can give bigger minutes and role for Haliburton and the other young players thus giving them valuable experience and in the long run you win more games by playing your vets huge minutes vs limited minutes AND giving bigger role to young players. Since at this point of the season all the future wins are meaningless and counter productive, the strategy should be limiting vet minutes and playing the young guys.
Also 2nd round picks by themself arent so valuable but the more you collect them, the more you increase the odds of finding super cheap contributors with restricted rights or being able to move up in the draft or using them to get guys like Davis or good vets when you are ready to be competitive. Thats why you probably shouldnt give two of them for a guy like Delon Wright at this point when the team isnt nearly good enough anyways. You'll easily find a guy like Wright in the free agency or trade market once you are actually ready to compete.
Disregarding the value of 2nd rounders is short sighted. One of them doesnt do you much but four of them can get you better odds in the draft or better options to trade up in the draft/trade for a vet.
