"They're maligned nationally, give it up each Saturday, and love bedazzled jogging suits. I'm speaking of the Real Housewives of Anywhere and Big 12 defenses. That is the popular perception and though there is some truth to it (at least according to the NFL draft), in 2012, the league will feature a few salty defenses to pair with its expected peppering of inadequacy. In fact - defense - not offense - will be the key differentiator in establishing this year's league hierarchy."
