http://sports-boards.net/forums/showthread.php?t=171272 "Joy reigns in Packerland, Brett Favre has struck out." I'm not saying that there's no rivalries in the North. What I'm saying is that one of the best current rivalries is Packers vs. Favre. When a rivalry with a single player outshines the rivalries between teams, how much do those rivalries really weigh in? Then add in the whole 'weak sister' argument (i.e. the Lions), and there you go.
