Avery is pretty much maximizing his ability. He could always shoot; his rookie struggles were more about nerves than ability. And we knew he would be a plus defender. And we also knew he was a tweener that didn't have the skills to run the point.
As for smart, we know he is not avery good shooter (something he's demonstrated for a while). We also know that he is a bit of tweener too, not really a PG, not really a SG. We also know he is not particularly explosive offensively and that while his strength helps him, he will not be able to dominate because of it. And we know he too is a plus defender.
So I fail to see the point. The issue for me is not about results; never has been. And if people are happy with a defensive role player, that's cool. He is growing on me in that role too. But let's not pretend he doesn't have glaring issues on the offensive side. Issues, that for all intents and purposes may prevent him from becoming anything close to a star.
