CHAMPAIGN (WCIA) -- Aaron Henry's first year as Illinois defensive coordinator was a learning experience. The Illini secondary coach was promoted to coordinator following Ryan Walters' departure after last season to become Purdue's head coach. Keeping the standard as high as it was with three NFL Draft picks leaving the secondary, including No. 5 overall pick Devon Witherspoon, was a tough job from the start. Illinois had the top scoring defense in the country only allowing 12.7 points per game last season. But the regression was more than expected, as the Illini struggled to stop opponents in several games, going from 1st overall to 92nd nationally this season, giving up an average of 29.4 points per game.
