Position of strength: Indiana Hoosiers

Last week on the Big Ten blog we looked at a position group for each team that needed some help from the incoming freshmen class. This week we'll be taking a look on the brighter side and breaking down the strongest link for each of the conference's 14 teams as they head into the 2016 season.

Now up: the Indiana Hoosiers

Position of strength: Offensive line

Key players: Senior OG Dan Feeney, senior OT Dimitric Camiel, senior OG Jacob Bailey, sophomore OG Wes Martin

2015 production: Indiana had the most productive offense in the Big Ten last season, leading the league with over 500 yards per game and a 36.5 ppg scoring average. The Hoosiers also had the second-best rushing attack in the Big Ten, at more than 210 yards per game and gave up the fewest sacks (13) in the conference despite throwing the ball more often than all but two teams. The offensive line, which paved the way for Tevin Coleman's 2,000-yard season in 2014, remains the underrated engine in Kevin Wilson's offense.

How they can help: The Hoosiers will have to replace their starting quarterback (Nate Sudfeld) and their leading rusher (Jordan Howard) in 2016. But as long as the O-line stays strong, there's a good chance the offense will continue humming.

The team got a big boost when All-America guard Feeney decided to return for a fifth season. Feeney has allowed just one sack in 37 career starts and should be the leader of the group this year.

Indiana will have to find a successor to Jason Spriggs, who earned some All-America recognition himself at left tackle. But the line will return three senior starters, plus another senior contributor in Wes Rogers. Martin made our ESPN.com all-freshman team in 2015, and the Hoosiers had three other freshmen on the two-deep by the end of the season.

Bet on offensive line coach Greg Frey -- one of the most underrated position coaches in the Big Ten -- figuring out the right mix by the time the 2016 season kicks off. He's already got one superb building block in Feeney, and Devine Redding looks ready to take over for Howard at running back. Indiana's success on offense in recent years has started up front, and that's not likely to change this fall.
