Tigers vs. Indians: Definitely one to watch for in the next 5 years. One team will win the division, and the other will likely win the wild card this season.Pistons vs. Cavs: Cavs won a 7 game series this season, but it is likely that the Pistons will not die yet. This rivalry is still alive.Wolverines vs. Buckeyes: Best rivalry of all-time, other than BoSox vs. NYY.Lions vs. Browns: NFL battle for who's the worst, but both teams are on the rise.Detroit owns in hockey, OSU owned last year in basketball (although U of M almost beat them towards the end of the year).
