Too many team sports = lack of moral development

I found this article on a study saying that members of team sports tend to lack moral reasoning - at least after a while. Here's the basic premise

"The environment of athletics has not been supportive of teaching and modeling moral knowing, moral valuing, and moral action," Stoll's 2004 study found, in part because there are few consequences for immoral behavior in sport.

With a broad stroke this study paints many athletes a morally deficient. Being someone that was an athlete and had to deal with jocks I can see some merit to the study - the athletes that are most applauded for their achievements tend to get the least amount of chastisement when they behave badly. Nonetheless, I know many jocks who have had most of their moral development as a result of being in sports. I think the study paints with too broad a stroke, but their is still a place for it.
