Illinois has fired offensive coordinator Garrick McGee and defensive backs coach Paul Williams.
McGee was brought in shortly after Lovie Smith was hired as head coach. He spent two seasons with the program but was never able to establish a formidable offense. In the 2016 campaign, the team averaged just 19.7 points and 315.1 yards per game, finishing 2-10 and 0-9 in the Big Ten.
Illinois started three different quarterbacks who combined for only eight passing touchdowns and 19 interceptions. The team ended the season last in conference with just 21 total offensive touchdowns.
Williams also spent two seasons with Smith. The Illini gave up 20 passing touchdowns during the 2017 season, second most in the Big Ten.
The moves were confirmed by the athletic department on Tuesday.
