Anybody that gets to 9-11 in the Big Ten is in for sure. Just how the system works.
I'd imagine they end up with 9 (Purdue, Rutgers, NW, Michigan State, Indiana, Illinois, Michigan, Penn State, Iowa).
That feels like 3 or 4 too many but that B1G patch on the front of the jersey seems to change the criteria.
Still more than a month away, so who knows what can happen. Big Ten looks like it's going to be a lot of muddling/interchanging roughly with #5 thru #10.
I agree with your estimate of 9 teams ... but I'd have Maryland instead of U-M to get the main 7 ... then two of Michigan/Penn State/Ohio/Wisconsin.
Edit: Wouldn't even be surprised w/ only 8 of BiG, depends on how much the bubble-area teams chase their tails. If BiG does get 10, it'll be glut of 11 seed/First Four, the way it's looking.
