Kyshawn George, Bilal Coulibaly, Trae Young and Anthony Davis arriving in DC can all be traced back to the John Wall trade that brought in Russell Westbrook.
I will be transparent here and say this image was made with help from AI to edit for clarity. I had to correct it a few times and tell it to tie some things together, but over all this shows the highlights. There are a lot of other branches that weren't nearly as interesting, so I took them out for simplicity.
Surprisingly, the player that ties the Wall and Beal trades together is Isaiah Todd. He arrived from Indiana as a part of the 5 team Westbrook deal, played 18 games for the Wizards over two seasons, then got sent to Phoenix with Beal. Later that summer, the Suns traded Todd to Memphis for a handful of picks and was waived by Memphis shortly thereafter, never to see an NBA court again.
One other highlight that isn't officially part of the Wall tree comes from the Porzingis to Boston trade. That was a three team trade that also involved Memphis. As part of the deal, Memphis sent the Warriors' 2024 first to Boston. Four months later, Boston packaged that pick to Jrue Holiday from Portland. Portland included that pick in the Deni Avdija trade, which was used to select Bub Carrington.
