Sorry, I still think you have it wrong. The term shouldn't be skill set, but physical talent set.
I played D3 at Washington and Lee Univ. In my time, we were nationally recognized, one year ranked nationally as high as #4. In my 3 years playing there we averaged about 20 wins. We beat Randolph-Macon, the D2 runnerup to UT-Chattanooga, James Madison, right at their switch to D1, UNC-Greensboro and our school annually played in the UVA tipoff tournament. My best friend covered Wally Walker. W&L is located literally feet away from VMI. The year before I started there, VMI made it to the Men's Elite 8. Great team and program, we went to a few games. We also played pickup with the Veemees in the spring. A couple of our players knew a couple of theirs from camps. They were not more skilled than us! They were physically better than us. Our center was 6'5, 6'6 or maybe 6'7, there's was 6'10. Same kind of comparison at each position. We worked on our games and dedicated ourselves to the game as much or more than they did.
