ATLANTA — After 15 years under Mark Richt’s leadership, Georgia is set to begin 2016 with a new head coach. Alabama defensive coordinator Kirby Smart, who replaced Richt on Dec. 6, will be on campus after coaching next Monday’s national title game against Clemson. Smart already has one big goal accomplished after quarterback Jacob Eason, one of the nation’s top recruits, decided to keep his commitment and enroll at Georgia this month.
