Every team has played some D-2 teams and a lot of the top point leaders in D-1 have put up big numbers against those teams. Those same players (top point leaders) have put up big numbers against tough D-1 teams. Basically the top point leaders are all quality players.
Some schools that have lack of quality depth will have players on thier team with lopsided numbers. Teams like Webb, USN, Farragut, Father Ryan dont have as much depth as teams like MUS, MBA, McCallie, CBHS. That what makes the things those players (on the temas of Webb, USN, Ryan, Farragut)do so special.
The top few players of these schools can compete with the top players of the "Big 4". The Big 4 just have more goood players.
