Finally tonight, it's the best play in college football so far this year. From a team you've likely never heard of, and from a player you're likely never to forget. It's "America strong." He's in for an easy touchdown. Reporter: In Alabama, at Samford university, family weekend. And college football player George grimwade, ready to debut his secret play. My stepdad. It sounds weird calling him my stepdad because he's always been my dad. Reporter: The senior offensive lineman decided to surprise his stepfather Michael, who has raised him since age 8. He doesn't have anyone to carry on his last name, and he raised me. Reporter: The two have developed such a close bond over the years that George decided to legally change his last name to honor his stepfather. I just want his legacy to live on forever. I don't want it to end with him. So, dad, I decided to change my name from George Andrew grimwade to George grimwade Musto. Reporter: George always knew the truth in his heart. Now he was ready to show the world the truth on his Jersey. I love you so much and you really do mean the world to me. I'm so happy that I can take on that last name with mom. Reporter: And just before the game, father and son, together for a talk they'll never forget. You know how much I love you, right? Yeah. How I always treasure the time I have with you? Yeah.
