CP3 is a top 10 player when he's clicking on all cylinders, and is literally the only reason the Clippers are staying afloat. Blake did well last time, but with his recent injury, would probably need a few weeks/months or even a season to recover entirely to still be the 1A/1B.
I take CP3 right now. He's a true floor general, can score, is nifty and shifty, while playing stellar defense and making everyone better around him. He has the benefits of Jordan and Griffin, so I wonder how CP3 would affect Horford, Crowder, or Bradley, who are all excellent catch and shoot players.
Isaiah Thomas is severely underrated. He's literally a few spots below CP3, and not by far. Eventually, if IT can keep up this resurgence, he can eventually surpass CP3 value wise.
