That's a good question. I only consider a player to be able to qualify for the position they played the most games at, but for ease of gathering stats, I took all their league games and favored the big 3 stats: pts, assists, rebounds and especially favored those on the leaderboards. Cisong and Lochaitis were on 2 leaderboards, so they seem like locks.
No idea how rating factors in, you might be on to something though.
