The only two teams alive in the Leaders division are Wisconsin and Indiana. Their game this weekend is the de facto Leaders division championship, at least as far as Wisconsin is concerned. If the Badgers win, they're going to Indy. If Indiana wins, they'll be tied atop the Leaders (at least, atop the list of teams that are eligible to win the Leaders), but they still have to go to Penn State and to Purdue.
Wisconsin, even if they lose to Indiana this Saturday, could still win the division, but they must then play Ohio State and at Penn State to finish the year.
Personally, I want Wisconsin to win out, but play two hard, physical games right before the championship game. Wear them out before we play them in Indianapolis and we should be able to put them away in the first half. Unchain Eric Martin, tell him to go blast O'Brien, and make them try to beat us on the ground with Montee Ball. They're not going to grind out a win against us that way, not if our offense can get a score or two early.
