In this trade, after the Embiid Injury, rather than try to compete this season the sixers decide to sell some expiring's of value to competing teams. Getting these picks they can use in the offseason to acquire more talent while keeping their salary cap space. Also adding Jalen Hood Schifino gives the sixers a young gaurd to develop/look to trade away this offseason to a young team.
Knicks get a good backup 3 & D Gaurd and forward with Melton and Covington, and don't have to give up too much draft capital.
Lakers get a bench/starting scorer in Oubre to help them this year while only having to give up Jalen Hood Schifino and a second.
