You win at Georgia, you'll always be a hero in Georgia.
You win at ND, you'll be a hero everywhere you go on the planet.
Hartman will go to the NFL regardless of where he ends up and how well he does once he gets there will have nothing to do with where he played in 2023.
He needs to get those ND sponsorships today, play out his NFL career, and then use the ND brand to get him some of the Brady Quinn post-NFL money. Don't make it more complicated than it needs to be Sam. Take the easy money.
