Just for kicks today I started looking at the schedules of the teams ahead of OSU to see if they have a chance to move up the standings.
Minnesota 5 tough games. They have a chance to pass Minnesota
Plays Wisconsin, @msu, Michigan, Purdue and @Maryland.
Iowa 2 tough games. I don't think they can catch Iowa
Plays Maryland and @Wisconsin
Maryland 4 tough games, probably can't catch Maryland
Plays Purdue, @Michigan, @Iowa and Michigan
Wisconsin 3 tough games, probably can't catch Wisconsin
Plays @Michigan, MSU and iowa
Purdue 1 tough game, no chance OSU can catch them
MSU 3 tough games, no chance
Plays @Wisconsin, @Michigan and Michigan
Michigan 4 tough games, still no chance
Plays Maryland, MSU, @Maryland and @MSU
Realistically, if the wheels don't fall off completely, they have a chance of passing Minnesota in the standings and that's about it.
