With John Kuhn and Zach Line scheduled to become unrestricted free agents, the New Orleans Saints are set to enter the start of the league's new calendar year potentially in need of a fullback. At least one of the players, however, is known to be on the team's immediate radar. The Saints and Kuhn have a mutual interest in the veteran fullback returning to New Orleans, according to a source familiar with the situation. The two sides have not met yet, but that could change leading to the start of free agency March 14. Kuhn is also pondering the next step in his career path, either remaining as a player or perhaps entering the coaching ranks, the source said.
