If you want to say your disappointed with smart, just say your disappointed with smart. No need to come up with some bizarre stat range based on a tiny sample to do so..
The sample is 80 games.
The stat range is, really simply, Smarts points, assists, rebounds, and field goal percentage.
I don't know what's so bizarre or misleading about that.
Once I actually look at the sample (again, please, take a look at the link posted previously), I try to look at other factors. Like minutes per game, games played, Win Shares, and so on. That's how I singled out the names I've mentioned earlier in the post.
Sure, you can mention Gary Payton if you want to believe Smart is like him, just by looking at their True Shooting. But their shot selection as young players was completely different, so that makes very little sense.
Smart, so far in his career, has been a combo guard with a low usage rate who has taken nearly half his shots from deep and rarely gotten to the free throw line. So I think if you want to make a reasonable comparison you have to look for other players who fit that description.
