The year before NO, he literally shot 48% from 3. In NO he was below 20%, and obviously unplayable if he shoots like that.
People like to say he needs to get in a rhythm or that he needs to create his own shot, but that doesn't really make sense. Shooting off the dribble is harder than a spot up shot, and I'm confident Jimmer would say that is true. And everyone wants to get in a rhythm but you don't really get that luxury as a bench player. You gotta come in and produce, especially if your role is to score.
