Yeah its likely his last chance. Im not holding my breath but I am rooting for him.Obviously the sample size is smaller for Dunn, but we just can't ignore how well he played. His defense sets him apart, and with his experience, he doesn't make many mistakes or poor reads. The dude is also a pretty good playmaker. I'm sure he trains hard this off-season to get a chance to show what he can do.
Would be good to have a guy of his archtype who could provide defense and offensive stability, even if he ends up being a 2nd unit floor general and a backup to whoever starts.
