Roper's firing continues the revolving door of coordinators under Muschamp, who now will be looking for his fourth offensive coordinator.
SC is not expected to fill the position until after the January 1 bowl game. Michigan's offense is ranked No. 101, averaging 354.9 yards per contest.
On the scoreboard, they're averaging 24.1 points per game, good for 98th in the country.
Coming into 2017, South Carolina's offense was expected to be the strength of the team.
Nationally, the Gamecocks 127.25 rushing yards per game is 108th. Turner is second on the team with 3 touchdowns.
Sophomore quarterback Jake Bentley has completed 62 percent of his passes for 2,555 yards with 16 touchdowns and 11 interceptions. He's also a threat on the ground - rushing 67 times for 86 yards and six touchdowns. Charlie Weis, Brent Pease and now Roper have run offenses at Florida and SC under Muschamp without lasting more than two years.
Roper has been the Gamecocks' offensive coordinator for both of Will Muschamp's two seasons in Columbia and also for Muschamp's last season in Florida. He has college coaching experience dating back to 1996.
McClendon played and then coached at Georgia for eight years before joining SC.
