In his freshman season at the
University of Alabama, Shelley was the backup placekicker for the
Crimson Tide behind
Leigh Tiffin and made only one appearance in which he missed his only field goal attempt along with making his only extra point attempt during that season. On January 9, 2012, he set a
BCS National Championship Game record and a career-high for field goals made against LSU in which he made five of his seven attempts. In the
2012 BCS National Championship Game, Shelley made kicks of 23, 34, 41, 35 and 44 yards. He finished his college career with a total 44 made field goals out of 55 field goal attempts and 172 PATs (an Alabama record), ranking him the 5th all-time leading scorer in Alabama history. In his Senior year, he was perfect, making every field goal and extra point he attempted, earning him the Vlade Award presented by the
Touchdown Club of Columbus as the nation's most accurate kicker. ==Professional career==
