For me losing the following would be a bad thing.
Evalds, Griffin (all 3 for me), Sa'u, Johnson (for his pace not a fan of the man himself), MCB (I still think he has much more potential than he realises), BJB (a full injury free season would have seen him score a hatfull), Hood, Patterson and Krasniqi.
Chase is an enigma, brilliant but prone to brain farts, I think that Sheens will be very aware of what he brings to the team going forward on match days but also very aware of the issues that follow him away from the field. I would still go to Hull and ask for a straight swap for Taylor but doubt it's a starter as he wants to move to Hull for family reasons.
