I think Barker is honouring a previous agreement to face Rotolo and if he was not so injury prone he would fight more often. It does seem churlish for the four to not be fighting each other. Macklin seems to think that he has left the other three behind. Barker seems eager to fight Lee and I can see no reason why that fight should not be made. Barker v Macklin is a hugely overdue fight that would be huge here in the UK but Macklin v Murray would be just as entertaining and could draw similar numbers. Will be interesting to see how Murray fares against Martinez and where he goes from there.
