His FT numbers have been sliding for years. His shooting from behind the arc, which at times been passable, pretty much disappeared this year. James is still a great defender, passer and rebounder, and a tremendous player overall, obviously, but he's faded a little. He does have the best 2FGA % among non-centers this year (Durant a close 2nd, Curry 3rd), and a lot of those shots he creates for himself. That's an incredibly valuable skill.
This thread, mirroring sports media at-large, has been prone to quite a bit of recency bias. Cleveland's still a great team. They are still unlikely to get swept. People were kicking dirt all over GS a couple weeks ago. People were also tongue-kissing Cleveland after what seemed like a pretty easy walk through their conference. Sometimes outliers happen. There's just no way GS is that many points better than Cleveland at home. They're better, but not by a ton.
