That's 21.3ppg, 6.9rpg, 4.4apg, and 1.6 spg, with 53% TS and an 11-7 record (if my math is right, which it might not be).
That's not too shabby.
Plus he's a proven defender, being All-Defense 3 years in a row.
You can't really do this exercise for one player though. You would have to do it for all players, and see how he ranks. (Even then, I don't think this is that good of an exercise).
But the players standing in Butler's way in your opinion from being in the top 10, what are their stats and record against those same teams, and is their defense as good?
