One word, Gustafsson. He and Shogun are two of my favourite fighters but I would love to see them go at it.
I was initially surprised at the idea that Shogun turned down a fight, but it does make sense. Word is that he's on very good form in training and coming off fight of the year with the current title challenger, fighting Glover is understandably not appealing to him. I think he'd accept fights with Gustaf and Evans, either one is a great match and makes more sense in the rankings.
Not sure why Dana is putting so much pressure on him to take the Glover fight, I hope this is sorted soon and Rua stays on the card.
