Both Paul and Griffin are free agents heading into this off season, so the Clippers can't trade them unless they do a sign and trade, and even then I think it's a pretty lame deal. Love and Griffin are pretty interchangeable at this point in my eyes: both capable of A+ performances but average a B+ at best. Kyrie for CP3 is a total dud on the Cavs part, though. Kyrie is 25 years old and likely has some of his best basketball ahead of him. CP3 is 31 and his best years are definitely behind him.
I understand your point about how they would fit into the system, but it's not like either team has a system that is greater than the sum of its parts. Each team is largely built around the play of their best players, not like the Heat or Spurs or even the Celtics.
Not only that, but we KNOW LeBron and Kyrie work well together. Better than well, LeBron has help Kyrie blossom into one of the best offensive points in the league. While I have no doubt that LeBron could make Paul a better player, I'm not sure that at 31 Paul is up for revamping his game.
The Cavs definitely need a big piece to compete with the Warriors and add to an offense that's prone to stalling out and a defense that's prone to failing altogether, but giving away Kyrie is not an option for them. Love yes, Kyrie no.
It pains me to say this, but you actually make a very very good point. Well done. Other than trying to get Griffin for Love I don't see what else they could do. Everyone in the media is talking about Paul George for Love or Melo for Love, however, I don't see how that would work. You'd definitely get more offense in that deal, but I think defense and rebounding would take a huge dive. The only way that it would work is that the Cavs would be playing small ball all year around because LeBron would have to move to the PF position. Unless they were to put PG or Melo at the 2; but then they'd need another big to fill in for Love. Which would be possible because if you put PG at the 2 that puts Smith back on the bench and then they could trade Korver or Smith if they wanted. I say trade Williams and Korver anyway. They did fuck all in the finals.
