I believe so. They are now 12-4 with 2 more games. Michigan is 12-3, Indiana 11-4, Ohio State 12-4, Maryland 12-4.
Maryland has 1 game left, they play Indiana. Best they can be is 13-4.
Indiana has 1 game left i think, against Maryland. Best they can be is 13-4 (unless big 10 website is wrong). They have had so many suspensions I don's know if they are going to make them up. But if Iowa wins out, Iowa would still win tiebreakers with Indiana.
OSU is 12-4 with game against Penn State and Michigan State.
Michigan is 12-3 with games against MSU and Iowa.
Way I see it is if Iowa wins out against Rutgers and home against Michigan, they would do no worse than tying for the title. Not sure who would win tiebreakers with Michigan or OSU, but it would still be a regular season title. Those are very hard to get and would be great to get.
