The big picture for the Big Ten involves four teams, all ranked, deciding the title over the next four weeks.

Waiting at the end is a big trophy and the guarantee of a Bowl Championship Series game berth. But each has a different path.

Wisconsin comes off a bye week with four games remaining, none against a team with a losing record.

Ohio State plays two of its last three games at home, but the one road tilt will likely decide its season.

Iowa hits the road for three games, wrapped around that important Nov. 20 home showdown with the Buckeyes.

Michigan State has the easiest road but is still hurting from its first loss.

Four teams, all ranked in the top 16 by The Associated Press and the BCS, have everything riding on a big finish in November.
