I hope JR has a big game and makes Cleveland his long term home. I think he may be our Stephen Jackson. As in the Stephen Jackson that played well for the Spurs. Both had some growing up today, both were talented and both seem better suited to play roles on a strong team then have too much asked of them on a weaker team.
I also think that that Lebron the leader will probably help here. Having the best player in the world in your corner and providing support has got to help. This may be the biggest change in Lebron on the return. Previously, he made players better on the court by getting them easy shots or plays but now he not only does that but helps them mentally by providing advice, support etc.
