Billy is probably one of the best players in this division. He's impressed me since he came back. His attitude and desire were never questionable, but his ability to get goals was, previously.
He now gets goals.
What has surprised me is the overall intelligence of the guy, he's constantly looking to play others in and like Baxter, he sees the intelligent passes. His decision making is excellent and whilst he does get dragged about, this works well with done and Adams in a three as they fill the gaps he makes. Billy's ball to Adams v Donny (I think) which played Adams in perfectly is the real snapshot of why we need him.
As for the Sammon debate. It's more complicated than play him/ don't play him. There are games when Sammon will be extremely effective, physical sides for example. We need a big lad like him. This is where Sammon looks shit though as he plays an entirely selfless game to allow others their chance to shine
Again, up top we don't have any problems... At the back though.... Oh fuck yeah we're shite.
