Happy Monday! Welcome back to the 2013 Preview Series, where we will take a look at the top 5 Hoosier defenders.  The defense seems to be the key to success for the Indiana football team for the last 15 years and each year the defense seemingly fails to step up and be at the very least mediocre.  2013 is going to be no different.  In order for this Hoosier team to live up to its potential the defensive unit must show some improvement upon a dismal 2012 campaign where Indiana gave up 35.2 points per game.  With the recent news of an injury to starting linebacker Chase Hoobler and the dismissal of Antonio Marshall, a corner who made some plays late in the season in 2012, in addition to the graduation of their two best defensive players, the job becomes that much harder.  Despite all of this the Hoosiers do have some talent returning on the defensive side of the ball, here are the top 5 defensive players for your 2013 Indiana Hoosier football team.
