After Mike Morreale left the Tiger-Cats in free agency, the team moved Amerson to the slotback position. The change of position placed him consistently on the starting roster for the first time in his career. Amerson's first receiving touchdown of the season tied a July game against the Stampeders, which the Tiger-Cats later won 34–31 in overtime. Two weeks later, he caught nine passes for 221 yards against the Ottawa Renegades. By the beginning of August, Amerson had emerged as "the top of the pile of Hamilton Tiger-Cats receivers" (ahead of Hall of Famer Darren Flutie) and was second in the league for receiving yardage. After an injury to starting running back Troy Davis in September, the Tiger-Cats utilized Amerson both as their starting slotback and backup running back, as they lacked a third-string running back. The majority of his production continued to come as a slotback. He recorded 147 receiving yards in the first game after being listed as a running back on the roster, including a touchdown catch in overtime to win 35–28 against the Montreal Alouettes.
