He'll be a star in maybe 5 more years, but leaving a champion-level team to go to the Rockets (for more money and a higher position) wasn't smart in my opinion.
He could have hung on at OKC for 1 maybe 2 more years, gotten a ring or two and then been a super-star anywhere he wanted to go.
He's good, but he's never been the type of player that can carry a team (and it showed in the playoffs/championship game). I love how he basically knew that the Thunder knew his tricks so when he went in with his side-step lay-up and tried to switch it up on KD, Ibaka was sure to let him know that $#!+ wasn't gonna fly around here.
Lynn and Harden both have a ways to go - and Parsons came out of nowhere to give their team a ton of well-rounded raw talent, but they're still young and don't really have enough leadership. Harden jumped the gun if you ask me.
Get out of my head!!! Seriously though, I agree with this post 100%. He jumped the gun a bit. He should have stayed for a ring. But I can't really blame a young guy for jumping ship for the serious coin they tossed him. Live and learn.
