I don't think Kobe will have a problem sharing the ball with somebody he knows is a highly competent creator/great shooter. Sorry but uh I don't see Kobe lobbying hard for the Lakers to trade for Nash if he planned on drastically limiting Nash's potential positive impact by sitting on the ball. Don't get me wrong, I know it's Kobe, and he's been the same for 16 seasons, but the situation is without precedent; 38-year-old Steve Nash will easily be the best backcourt partner Kobe's ever had. I believe at this point, Bryant just wants rings, and is more willing than ever to make the concessions necessary to attain them. Whatever, even if he isn't and everything is turrible, I'm still drooling over the idea of a Nash-Gasol PnR.
I just mean Nash without the ball in his hands most of the time is limited in what he can do for your team. He still brings the shooting but using him as a spot up option is a waste of his talents. I think it very hard for Kobe to unlearn the ball dominating habits of a lifetime. Some interesting lineups when they don't share the court though.
