FILE - In this Sept. 12, 2015, file photo, Clemson head coach Dabo Swinney disputes a call by an official during the second half of an NCAA college football game against Appalachian State, in Clemson, S.C. All eyes around the Atlantic Coast Conference will be on officials this weekend. No one wants any faux pas, not league officials, coaches, players and especially the refs _ not with games like Florida State-Clemson on the schedule. (AP Photo/Richard Shiro, File)
