Who is the best team in the B10 over the past 4 years? You would think the answer would be WIS since they have gone to all of the last three rose bowls, or OSU who has been undefeated for the almost two solid years.
If you make the decision based on B10 wins you would have to go with MSU who has the most (OSU has one more but had to vacate all their 2010 wins).
However to truly be considered the best you need to be able to beat the best, not just run up the score on bad teams. So I looked up how many wins each team had against MSU, OSU, WIS, NE and UM since 2010. The answer may surprise you if you are a WIS or UM fan. MSU and OSU both had 8 wins against the other top teams (although OSU did have one vacated), NE was third with 6, WIS had 4 and UM 3.
As a WIS fan you may argue that UM is not really a top team so MSU's beating them 4 out of the past 5 years should not count. So if you only consider how many wins WIS, OSU and MSU have against each other over the past 4 years you amazingly come up with the exact same answer. OSU has 4 victories against MSU and WIS, MSU has 4 victories against WIS and OSU, while WIS only has two wins against MSU and OSU.
So when WIS tries to lobby for a BCS bowl game once again this year remind their fans that MSU has won more games than they have over the past four years. Additionally they have done it playing a harder schedule, beating more than twice as many of the top B10 teams in the process. You could also point out that MSU has beaten WIS all three years they have met.
