I don't see anything strange with Jones' response. To have people bringing up Rashad all the time when he has a huge challenge in Shogun ahead of him and needs to stay focused. Of course it's annoying to him.
Having said that, I think Rashad bases who to fight solely on what he thinks is best for his career (i.e. get the belt). What risks and potential benefits are involved in taking a fight. Not any notions of friendship. But that's just what I think.
