Last season, Indiana had arguably the most explosive offense in the Big Ten.
Only the Ohio State Buckeyes averaged more than the Hoosiers' 38.4 points per game and 508.5 total yards per game. Indiana's 306.7 passing yards per game were the most in the conference.
But that offense, which was already going to look a lot different thanks to some departing wide receivers, is going to be even more different following Tuesday's announcement that quarterback Tre Roberson would be transferring.
Roberson served as one half of a two-headed quarterbacking monster alongside Nate Sudfeld a season ago, the more run-oriented one of the two. It took until the second half of the season for Roberson to get a bigger role. He had two big passing games (288 yards vs. Michigan and 273 yards vs. Purdue) and rushed for a total of 233 yards in the season's final two games against Ohio State and Purdue.
"We appreciate and thank Tre for his contributions to our football program both on and off the field," Wilson said in the team's release. "He is an outstanding player and a great young man. We wish him well as he moves forward with his career."

"I want to thank the coaching staff, my teammates and Indiana University for all of their support over the last three years," Roberson said. "My time in Bloomington will always hold a special place in my heart. I wish everyone at IU all the best as I move on to the next chapter in my life."
Sudfeld now becomes the man in Bloomington, which it seemed like he should have been most of last season. His numbers were excellent, averaging 293 yards through the Hoosiers' first five games. Those took a dip as Roberson started seeing more of the field, but Sudfeld still finished with 21 touchdowns, the third-highest number in the Big Ten.
On the flip side, however, if Wilson does want to continue employing a platoon system under center, his options won't be as battle-tested. Roberson joins Carson Coffman, the Hoosiers' third QB last season, in leaving the team, leaving Sudfeld as one of six quarterbacks on the roster. The only upper classmen, though, are Sudfeld (junior) and Max Matthews (redshirt junior).
