But it soon soured, and by the end of last season, which the Rockets finished 41-41, it was clear that Houston had one too many top dogs in the locker room. "It was confusing," says Rockets guard Patrick Beverley. "I've got Dwight telling me I need it in the post, I got James telling me I need it on the wing."
Without context, it's hard to know what "it" refers to. Because the passage refers to basketball and is referring to what players are (supposedly) saying in game; I'd say that "it" refers to the basketball.
I hope this helps,
