Over the last few years the offensive line has become the cornerstone of the Indiana offense. Offensive line coach Greg Frey has produced two All-Americans, an NFL draft pick (Dan Feeney will surely be another after the 2016 season), and his offensive lines have paved the way for three 1,000-yard running backs in the last two seasons. In order to keep up this torrid pace the Indiana coaching staff has to find the right players to mold into high-quality Big Ten linemen. They may have planted an early seed with an offer to a class of 2018 four-star offensive tackle, Trace Oldner.
