the grandmother has a heart condition. Almost every elderly person has some sort of heart condition. This is 100% because he doesn't want to move from home and doesn't want to go to a school where he will be buried away and get no national attention. If he wants to go to USC, than that is 100% fine. However, if he wants to play this season, than that is insane. You can't sign a NLI and then back out and not sit out a year. If he really needed to take care of his grandmother, than he would be more than happy to put his basketball career on hold and spend time with her. I think he is jealous of all the attention daniel is getting and doesn't want to be left out. The videos of them on youtube scream extreme sibling rivalry.
