Lead your alma mater to a National Championship as a head coach in Dynasty (Coach Contracts on).

When you create a coach in dynasty, make whatever your favorite team is the alma mater and get signed to that team. If you want to make it easy, try getting signed with Alabama. You can also sign up for one of the teams for the Welcome to the Club achievement (S. Alabama, Georgia State, or Old Dominion.) But I would stay on a higher ranking team to knock out other achievements while youre at it.
