One reason I think this team has regressed with him coming off the bench, is he's playing most minutes beside Lowry/Lucas. It's too ineffective because Calderon and Lowry are two different guys. The 2-guard lineup works better when the pass-first guy is handling the ball, and the more aggressive guard off the ball.
One example was last season when we had Bayless starting at the 2, with Calderon at the 1. Let's face it, Bayless and Calderon played really well together.
Jose is a very good point guard, and he made his name/living in Toronto as a back-up, there's no doubt he is a good back-up. Is he good off-the-ball? Well, he's clearly better when trying to create for others..
