Indiana spent plenty of time in 2013 watching opposing offenses roll up yardage and pile up points, but the Hoosiers hope new defensive coordinator Brian Knorr delivers a new mindset and better results. The Hoosiers host in-state rival Indiana State in Saturday's season opener, the first test for a defense that surrendered 35 points or more 10 times in 12 games last season. Improvement on defense is a must for an Indiana squad that averaged 38.4 points scored last season and hands the offense full time to junior quarterback Nate Sudfeld.Sudfeld threw for 2,523 yards and 21 touchdowns a year ago, and will rely on junior running back Tevin Coleman, who rushed for 958 yards and 12 scores while an inexperienced receiving corps gains experience. The Sycamores, who won once in Mike Sanford's first season as head coach in 2013, return third-year starter Mike Perish at quarterback but have lost 13 of their past 14 games and went winless in Missouri Valley Football Conference play last season. Indiana leads the all-time series 5-0, scoring the second-most points in school history while throttling the Sycamores 73-35 in last season's opener.TV: Noon ET, ESPNews.
