If we're assuming WI wins out, I can compare a 2 loss MSU team to them. One coming against marginally-ranked Notre Dame on the road, one against a 25 game win-streak OSU in the title game. I can't imagine voters dropping MSU far for that loss, and coming in to that game they're likely close to being a top 10 team (they're 17 right now compared to WI 24). My money would be on MSU over WI in that situation to be in the top 14 and picked by the Rose Bowl.
Back to the dream scenario. A Gopher team that has 6 consecutive wins, including Nebraska, PSU, Wisconsin, and MSU, could very well be ranked 10-14th coming in to a BT title game. It would be unfortunate that a team with losses to Michigan, Iowa, and OSU would drop out of the top 14, but I wouldn't doubt it. We may actually fare better in a scenario that sees us win out but MSU's only loss comes against us, keeping us from dropping in the BCS rankings.
I don't buy that we don't travel well. We haven't been invited to a good bowl game to test that theory, so it's bogus. Nashville in 02, 04, and 05, El Paso in 99 and 03, and Tempe in 06, 08, and 09 are not exactly great destinations or prestigious bowls. Add in that our teams typically finished their seasons on a disappointing downswing and it's not surprising attendance was sub-par, but throw an Outback, Capital One, or Gator Bowl our way and people will go.
