Wouldn't do it. I don't like the fit of McCollum next to Lillard, plus neither of them is young enough to play alongside Tatum going forward. Having said that, I wouldn't be against the idea of swapping backcourts with the Thunder.
OKC in: Kemba + Brown
Boston in: CP3 + SGA
https://tradenba.com/trades/rGOYXlrYGObviously, Paul's contract sucks, but it only runs for 2 more seasons. Btw, Lillard's and McCollum's contracts suck as well. For instance, Lillard will get paid $50,750,000 in 2023-2024! He'll be 34 years old in 2024.
Right now, imo:
CP3 > Kemba
SGA > Brown
We'd also save about $11.7 million next season, hence we'd probably reset the clock on the repeater tax.
But then again, I'm super high on SGA. I bet many of you guys would rather have Brown over SGA and/or Kemba over CP3.
Ideally, I'd love us to pair Brown with SGA. Not sure how we could do that without sacrificing Tatum (which obviously ain't worth it).
