Nobody thinks Smart is a good shooter though. One of the reasons he has so many open looks is he is a terrible shooter.
I disagree. I think opponents generally defend Smart like he's a competent shooter. They don't treat him like he's Steph Curry, but he doesn't get the Tony Allen treatment, either.
The fact is that to be an effective role player a wing or guard in today's league needs to be at least a theoretical outside threat.
My position on this is that it's better for a 33% three point shooter to act like he's a 40% three point shooter than visa versa. I think opponents often defend shooters based on an idea of how good those shooters are rather than what the stats say, and that idea is formed in large part by "hot" shooting games rather than shooting percentages over a large sample.
Smart's not perfect but he's not the problem and I love him the way he is. For me that's period, end of story.
