College football Week 13 preview: Five best games to watch this weekend

Week 13 of the college football season will reveal the truth about who's for real and who's not. Take No. 5 Indiana, for example. The Hoosiers have blown past most of their opponents this season, are 10-0 for the first time in school history and first-year head coach Curt Cignetti has already signed a new contract. How will they handle the pressure of facing No. 2 Ohio State in Columbus? Can they pull off a massive upset?

Then, there's No. 16 Colorado, which is riding a four-game winning streak and controls its own destiny in winning the Big 12. Standing in its way this week is unranked Kansas, which has sneakily beaten two ranked opponents in consecutive weeks. Will the Buffs be the Jayhawks' next victim?

Meanwhile, No. 19 Army remains undefeated and takes on its first ranked team of the season in No. 6 Notre Dame at Yankee Stadium. Can the Black Knights keep their perfect streak going?

With that, here are the top five games to watch this weekend:

No. 5 Indiana at No. 2 Ohio State ( 12 p.m. ET on FOX and the FOX Sports app )

Indiana is one of the most pleasant surprises of the year. During the preseason, the Hoosiers were ranked near the bottom of the Big Ten. But new coach Curt Cignetti has inspired a team full of transfers, and now Indiana has a huge opportunity on Saturday. One of the knocks on IU, however, is the fact that it has yet to play a ranked opponent. Teams can only play the teams on their schedule. It's not the Hoosiers' fault they didn't draw Oregon or Penn State and that defending-champion Michigan isn't the team it was last year.

Now they have a chance to make one of the biggest statements of the season vs. No. 2 Ohio State in Columbus, with conference championship and College Football Playoff
