As far as the CP3 contract. He is a guy who likely has a clear plan for when he retires and what he does after that. That guy is smart and based. I have a hunch that he plans to retire after this deal is over. So, his contract becomes a very valuable expiring for a team that wants to do something big in the free agent market. Expirings do not seem to command as much value as they once did, but that would be his value to the Suns. His deal coming off the Suns books does not help them much, but it could help a team like the Lakers a lot--a team with limited picks going forward needs to be able to use the free-agent market.
He would likely be traded and retire.
So a deal like Paul to the Lakers for LeBron or AD, could give the Lakers a clean slate salary-wise and go for a top free agent. Not proposing a real trade, just kinda throwing example scenarios out there.
