binary adjective \ˈbī-nə-rē, -ˌner-ē, -ˌne-rē\
- of or relating to the use of stable oppositions (as good and evil) to analyze a subject or create a structural model
Rather than view Alabama's 2013 defense as potentially sub-par, perhaps a better explanation for the scrimmage stats is that AJ McCarron and Amari Cooper are just excellent players. This is very much a binary situation, where one unit must thrive at the expense of the other. After all, one player is already a serious Heisman candidate, and the other is one of the nation's best receivers.
