Well when I watched against Hinckley, McSheffrey was very vocal and encouraging towards the younger players. My main point is that he represents the fans (as he is one himself) and this can be recognised on the pitch.
Overall the way I see it we have 3 stand out candidates; Sheffers, Kilbane and Wood and in my eyes only one of them is guaranteed to start and that's Sheffers. Wood faces serious competition for centre back (though for what it is worth, I believe he should start). Whatever everyone says about Kilbane and his fitness, he's 35 years old and will be 36 midway through this season and last year racked up only 9 league appearances. If he's good enough and fit enough then I'll be happy to be proved wrong, but I don't believe he will captain the side based on the fact he may be used as a bit part player, particularly if we get Jennings in.
McSheffrey is a local lad, who has played Premier League football and has the experience. He is of a good age and I think giving him the armband would mean a lot to him, and this is why I think he is deserving of it!
