I honestly think that we aren't being shown the whole story with Andi/Josh. She is from Atlanta. If you are from Atlanta, and you have a father who loves Georgia football and probably lots of friends who love Georgia football, you know damn well who Aaron Murray is. And yet the show is acting like she's just now learning about who he is and what a big football player he was/might be in the NFL, and how life works in a Southern family with a huge college football star. And in Nick's HTD, when he tried to get her to say "Go Packers," she refused because she is a Falcons fan. I'm not trying to say she's a super huge fanatic, but I think she knows more about this whole football thing than we've seen.
Also, she's being given an unfair rap here. Her talking heads were not "look at meeeee" at the Josh HTD. They were "I know everything with Aaron is a really big deal right now, but I hope they pay attention to Josh because he's also going through something really big." Her comments were actually focused around him and how she wanted him to get some recognition in his family - again, IMO, because she has known the whole time just how much his family is probably all about Aaron. It wasn't some big surprise.
I think she is a lot more comfortable with the Murray family situation than they want to show us, because it may actually push things too far in Josh's favor.
