I will probably get slated for this, but the core of the team is pretty good. Certainly the spine has experience and is proven at this level. We need to keep hold of Long and Maguire, of those with contracts ending the only one I would offer one to is Matty Harriot.
With Long in goal and a defence of McMahon, Collins, Maguire and Hill we have a very good defensive unit. I would want cover though ..... and not Higginbottom! With McFeazden, Murphy and Flynn as options out wide then I think we're ok in that area. I'd be looking to bring in some competetion for Doyle and K Mac, but they proved in 2011/12 that they can be a very good midfield pairing. Up top is a major problem area. It would br great if we can get Miller fit, but if not we desperately need reinforcements. Porter is ok, and could do a job, but he is so limited.
I actually think with the current squad and a decent manager we should be pushing for promotion. the decent manager would need to be good tactically, make a few shrewds signings (such as Wilson's signings off Murphy, Blackman and Miller) and be a good motivator. The problem is finding someone. We saw how hopeless this team looked under Morgs (appart from Brentford and Swindon where he fired them up) and Wilson had clearly lost it too.
