Apples and oranges. Obviously the athletic tests are going to be dominated by small players. If you want us to take that seriously, you have to sift through the data and show how Kanter did compared to the other big men, PF/C players. I started looking at that, and the first big man I ran across was at #13, JaJuan Johnson. But I didn't want to take the time to look through the whole list.
You can sift through data yourself, or you can trust the conclusion DX made on this: "Enes Kanter didn't stand out in any of the metrics covered in the combine, but didn't finish in the bottom-5 of any of them either. He measured taller than expected, which is a plus, even if he's only in the middle-of-the-pack athletically."
