With preseason practice entering its third week on most Big Ten campuses, lineups are taking shape. Still, many competitions around the league have yet to be resolved. We’re looking this week at fights for playing time that figure to shape the complexion of Big Ten teams, division races and bids for championships.

Next up is the Indiana Hoosiers.

Top position battle: Right tackle

Aside from quarterback -- a position group unto itself -- Indiana returns more experience and skill on the offensive line than at any spot on the field. Center Jake Reed, right guard Dan Feeney and left tackle Jason Spriggs have combined to start 62 games, providing optimism that the Hoosiers can open holes for running back Jordan Howard and protect QB Nate Sudfeld.

Redshirt freshman Wes Martin has matured quickly at left guard, leaving the booked opposite Spriggs as a competition between redshirt freshman Tim Gardner and fourth-year junior Dimitric Camiel.

Camiel started five games in 2014, including four at right tackle. He trained some during the offseason at left guard but has worked primarily at tackle this month after Ralston Evans received a medical hardship, cutting short his career by one year because of injuries.

Gardner sat out last season after transferring from Ohio State and brings impressive credentials as a prospect out of Indianapolis.
