Nation correspondent Dave Zirin appears on Morning Joe to weigh in on the year’s top sports controversies. Rounding out the year is the Tiger Woods scandal, but lest we forget that Rush Limbaugh tried to do some NFL bidding, that Caster Semenya raised questions about gender and sex, and that A-Rod’s steroid use was revealed, Zirin reminds us of the political nature of some of sport’s biggest headlines.
