Clarification: PerfectGame is about developing youth baseball. They even have a college summer league where Gorski and Sallfrank are playing. They do provide recruiting information but as I said it is from the kid's perspective.
I suppose the Rivals site coild do more and at some places they do, but that is a function of demand and supply. Do the customers demand it, does the team supply it.
To me the fault with regard to IU baseball info goes to the athletic department nad the internal IUHoosiers.com site, and by extension to the baseball program itself. These school sites should be about building fan interest and one way to do that is by providing information about the team and players. For some reason the IU site is lacking with regard to baseball.
