I'm not discounting the importance of rebounding but I am questioning this line you've drawn: double digit rebounds for an individual player.
32 conferences, 350 teams, which means over 1000 scholarshipped players. How many of them average double digit rebounds in a game? I'd have to look but I'm willing to bet is less than 5%, likely more like 2-2.5% of players average those numbers. How many ranked teams have a guy with those numbers (double digits?) One? Two?
The Tide has been pretty consistent in having five or six guys who have at least four rebounds a night. The two games you've mentioned had a high number of rebound opportunities which is a caveat in and of itself.
Personally, I like seeing that many guys with around five a piece versus two guys having 2/3rds of the boards.
