Do sports teach negative behaviours?

This article states that high school athletes are more likely to cheat and bully than those who do not participate in sports.

As a non-athlete, I have absolutely no trouble believing this. I've seen it over and over again, and I would imagine it only gets worse as the pressure intensifies - as it does in situations where there are college scholarships at stake. I've heard people decry the lack of sports scholarships at Canadian universities, but it does do this, at least - it takes some of the pressure off young people to succeed in their sport, at any cost. If the cost is their honesty or empathy, it's too high.

Of course, there's always the possibility of a disconnect between causation and correlation. It's possible that the people who push their kids to succeed in sports at all costs are also the people who think success is worth it at any cost in other areas.

So, friends list: what do you think?
