Disagree. I don't think Turner's a future starting PG on a contending team, but he's a viable
PG on our current team. Smart is getting better and may one day soon play Turner to the bench, but there's no reason not to let that happen organically, instead of forcing it. Furthermore, Smart's shooting playing off the ball has really improved, while his shots off the dribble haven't. There's value in letting Smart develop one portion of his game at a time instead of throwing everything at him all at once.
I also don't by random internet commenter's observation biased opinions that Turner only passes to Sullinger. The data exists, and is easily demonstrable if true. What is true is that Turner is on the floor with Sullinger more than any other player, but that's it.
