All of this leads to no great players really standing out from the rest. Just a couple examples:
PPG
HD Smith DI leaders (full season currently finished):
1. Timothy Axelson Sr. SF Xavier 22.0
2. Leo Smith So. SG Tennessee St. 19.9
3. Robert Cassidy Sr. PG Clemson 18.2
4. Robert Eudy Jr. SG Davidson 17.8
5. Christopher Dobson Jr. C Coppin St. 17.1
2008-09 college basketball leaders (ESPN):
1. S. Curry, Davidson 28.6
2. L. Hudson, UT-Martin 27.3
3. J. Taylor, C Florida 26.2
4. D. Holston, Chicago St 25.9
5. S. Jackson, UTEP 24.2
RPG
HD Smith DI leaders:
1. Donald Neary Jr. C Bradley 10.1
2. Valentin Russo Sr. C Vermont 9.8
3. Ryan Sanders Sr. C Coppin St. 9.5
4. Erick Markle Sr/5 C TX State-San Marcos 9.3
5. Jesse Taylor Sr. C Quinnipiac 9.2
2008-09 leaders:
1. B. Griffin, Oklahoma 14.3
2. J. Bryant, Santa Clara 14.2
3. K. Faried, Morehead St 12.8
4. D. Blair, Pittsburgh 12.2
5. L. Harangody, N Dame 12.0
Both stats are full season stats, Smith played national championship games a few days ago, which is why I used last season's real college stats.
If you care to look at any other world, or any other statistic category, you will notice all the averages are significantly lower because there is a lack of skill variation in HD DI. If a majority of post players had mid to high 80s REB, and three or four players with 92-96 (not 100), you would see Rebounding leader boards reflecting real life.
There is also the case of an above average player playing in a below average division, such as John Bryant of Santa Clara (above). But he is still pulling down more boards than any 'great' HD player because he stands out.
