ND is unlikely (to say the least) to be seeded any higher than 7 since both the SEC #2 (unless the single digit possibility of A&M being that team) and the Big 10 #2 will be seeded in the #5/#6 slots.
And it is highly probable that the #3 SEC/ Big will also be seeded above us.
At that point we are sitting at #9 as about our highest possible seeding, unless some strange things happen in the next 3 weeks.
