For starters, I'm not sure how willing any of these teams would be to doing this trade. For philly its obvious, they sacrifice the 3rd overall pick in order to get out of PG's albatross of a contract, and get expirings and cap relief while taking a lump with vando's contract

For memphis, they get a solid young prospect in Dalton Knecht, along with expiring contracts and 3rd overall pick which is extremely valuable

For the Lakers, they take probably the biggest risk as they tie up their entire cap space for some time to come as they lock into a 3-4 year core of Luka/PG13/AR/JJJ without any real way of getting out of that if it doesnt work. But the upside is Luka/AR/JJJ are all around the same age and is a good core to build around for next 8 years with the smallest of hopes that PG13 last year with 76ers was an aberration and he will somewhat resemble the PG13 from his last year with the Clips
