I would delist Johnson and Petts before Cogs but thats it. The other players I would delist including Simmonds, Bowden, Brown, Polak, King (trade) and McMahon (trade), would all have more value to the list IMHO, than Cogs would.
It's sad to say but with our midfield improving, Cogs is far from a crucial component of the team now. We have far too many players who play a similiar role to him but who are both more skillful and faster on the list for us to keep hoping he will regain his B&F form. The same can be said with Browny but at least Brown still has the finishing skills.
I think unless he does something miraculous for the rest of the year, at 27, it is time for him to more aside for a younger player.
