the PG13 trade is one example of a team going all out and mortgaging their long term future to get one player. The AD trade is another example of that but fortunately for the Lakeshow it already paid off in year 1. LAL doesn't have any first round picks from 2022 till 2026 plus they gave up Lonzo Ball, Josh Hart and Brandon Ingram.
Kawhi can opt out at the end of the year and be free agent. If he signs with another team then essentially the LA Clippers lose the main byproduct of that PG13 trade which is the signing of Kawhi.
Ya gotta love both LA teams. Both teams swinging for the home run back in 2020 free agency.
