I think Jesse may be receiving pressure from somewhere to go to Tennessee because if he was really wanting to go to USC he would have committed already,I''m just saying that there may be someone in his ear wanting him to go to Tennessee.
Also,It could be that he really wants to come to Tennessee,but he doesn't want to let his family down.In that case he may be trying to make his family realize that Tennessee is the best place for him,and bringing them with him on another visit could do just that.
