yes, it's easy. You can probably sell them on stubhub the day you get them and make 30% or more. Wait until a couple weeks before the game and you may double your money. It all depends on how well those two teams do throughout the season, but neither Bama nor LSU are going to be in the high risk category.
Now, whether it's legal or not is another story. Rather than bore you with details, though, just do it on stubhub. You won't have any issues and while they charge you 15% commission, it's worth it to me because it's so damn easy.
