In a statement , the groups said there is no evidence that Manziel , who made history last year as the first freshman to win the Heisman Trophy , received money in exchange for autographs . In addition to serving his suspension , Manziel will address the team about lessons learned , and Texas A & M will revise its education concerning student-athlete autographs . `` Student-athletes are often asked for autographs from fans , but unfortunately , some individuals ' sole motivation in seeking an autograph is for resale , '' NCAA Vice President of Academic and Membership Affairs Kevin Lennon said in the statement . `` It is important that schools are cognizant and educate student-athletes about situations in which there is a strong likelihood that the autograph seeker plans to resell the items .
