The whole idea that both teams have to be good at the same time to be a rivalry flies totally in the face of tradition as far as sports go.
The rivalry between Army and Navy has existed forever and it has nothing to do with the relative strength or weakness of that year's team.
I'm not talking about tradition. I'm talking about this particular case and these 2 particular teams. If they're both winning in the regular season, and then playing each other in the playoffs, watch how quickly this rivalry flares up.
