I'm not really big on the idea of "building around" a player. I think you should put the best team together possible with pieces that fit together. You build a team to fit a style of play or a system not one player.
I think the "build around" idea is a little bit confused at times in how we talk about it.
Some players are so good they make constructing a roster much easier, because the players around them don't have to do as much to succeed.
I don't agree that only super-duperstars like Durant and LeBron fit in that category. There are at least 10-15 guys in the league, I'd say, who make roster construction much easier because they are so all-around good.
Other players -- most players -- do some things well, but also have significant limitations, so they only work as components of a whole, not as a centerpiece.
Then you have guys that have such pronounced strengths and weaknesses that the team's gameplan must be tailored to them in order for them to contribute at all. Typically it's a primary ball-handler without a jumpshot, or a post-scoring big man who struggles with rim protection and team defense. Those players make roster construction harder, even though their talent may be worth it.
I think IT fits in the "component" category. His defensive limitations are an issue, but I think he could fit on any team whether as a starter or in a bench role, especially because he has shown he can have success off the ball as well as on.
