I would do that trade immediately if offered. Jrue Holiday is already a huge upgrade over CP3 minus 10 mil a year. ET is a downgrade from CP3 however AD is AD. Screw it give them the 4 unprotected first round picks 2020/2022/2024/2026 that way we can't use them in the future for LT savings.
Look, with Golden State out of contention, if we sign AD, we would clearly be favorite to win the West. Morey needs to go all in. Harden is still in his prime. Time to pull the trigger. Raptors gamble and paid off. Time we do the same. Get AD and Harden together, we win West.
