And this is for the past 10 years? If so, it seems rather meaningless to me. For this year, it would be useful.
I think it is useful as a quantification of program "reputation" (e.g., fun-and-gun versus grind-in-out depending on how far is your bias in either the offensive or defensive direction) and "standing" (e.g., how good are you, how far to the upper-right). Iowa State is known for its offense and is to the bottom-right, and K-State for its defense (and to the upper-left).
Ask any one of us the "royalty" or top 5-6 programs of college basketball right now, and they would probably give you a list a lot like Duke, UNC, Nova (two championships lately), Gonzaga (almost won one), Kentucky, Kansas, and maybe like Virginia. This quantifies it.
