I myself would go for Boggy, Hume and KO. KO has been doing fine with supplying decent balls to the forwards and scaring the oppositions defense lately and it looks like he enjoys that roll, and maybe pick up on a few loose balls on the way.
yeah but you can't have 3 strikers when we also have Hammill and JCR? I'd keep OJ as an impact sub, maybe start him in the odd away game. Until Hume is back i'd play Boggy and Hume. we have 4 decent strikers though which is good. I'd send coulson out on loan for a year to get his fitness and confidence back.
Its important that hume is not rushed back. So if the other strikers are doing well we can bring back slowly and that's good for barnsley and hume.
