DeRozan is not a guard unless you think Ball or LaVine is a forward. And with the injuries Caruso and Green have also been starting. Yesterday, they started White, Dosunmu, and Green with all the guys out, so DeRozan basically started at PF. bball-ref says he has played 6% at SF, 84% at PF, and 10% at C. No guard minutes at all on the season. In other words, DeRozan is as much a NBA guard as I am.
