I think using the previous trades of 4+ picks for valuation is inaccurate in the current market because way more teams are super conscious about avoiding the salary cap aprons.

Having locked in low salary players on rookie deals is huge for team building so picks are a bit more valuable especially given a lot of teams don’t have their own picks anymore.

I would say the exception to this is for a true tier 1 talent like Giannis since those players are worth the risk of an all in play but someone like Trae or Morant who have clear risks plus their salary impact to the rest of team building makes their trade value lower than in previous CBA agreements.
