1) That's irrelevant. "Other groups probably have the same issues" doesn't diminish what is actually happening in this group. 2) We have other sports to compare it to, and other sports have their issues too, no doubt (Semyon Varlamov's dropped domestic violence case for one, off the top of my head). But subjectively, it doesn't seem like it's happening with nearly the frequency that it is in the NFL. EDIT: I guess it's not so subjective after looking at the deadspin link.
