Iowa's football staff makeover will extend beyond Brian Ferentz replacing retiring offensive coordinator Greg Davis.
Two other Hawkeye offensive assistants, receivers coach Bobby Kennedy and running backs and special teams coach Chris White, will not have their contracts renewed for the 2017 season according to coaching website FootballScoop.com.
During a news conference Monday, Ferentz did not discount the possibility of additional staff changes.
"With Greg's announcement last week, it opens everything up and first consideration is the coordinator's position,'' Ferentz said. "Get the right person in that seat and then, what's the best way to move forward. I've been considering everything and I'll continue to do so.''
Both Kennedy and White joined the Hawkeye staff in 2013, Kennedy arriving from Colorado after previously working with Davis at Texas and White added to the staff after four years as the special teams coach with the Minnesota Vikings.
Iowa ranked in the bottom half of the Big Ten in every major offensive statistical category during the 8-5 season which ended last week with a 30-3 loss to Florida in the Outback Bowl.
The Hawkeyes were 10th in the league in scoring at 24.9 points per game and ranked 12th among the Big Ten's 14 teams in total offense, averaging 325 yards per game.
Despite having two 1,000-yard rushers in a single season for the first time in the program's history in Akrum Wadley and LeShun Daniels, Iowa ended up eighth in the Big Ten in rushing with an average of 171.8 yards per game.
Iowa's passing numbers rated even lower. The Hawkeyes were 13th in the league in passing offense, averaging the program's worst yards per game since 1981 with its average of 153.2 yards per game.
