He's plenty good enough to BE in the P6. However, most of those teams wouldn't use him as a 35 mpg guy, use him out of position as full time point over multiple seasons, or afford an unlimited green light.
In a complimentary role, he could be a solid contributor on a good team. Here, his minutes were in disproportion to his limitations.
And I say that full well acknowledging the two solid back-2-back years he's had. Still would have liked to see him play fewer minutes, in a backcourt rotation with better players.
