Ian RoyalE. Andrew Pearce is the most logical option of those. As above, the others aren't guarenteed a long-standing spot at the moment.
I don't understand how Guthrie isn't guaranteed a long standing spot. He's been clearly one of our best players. And we have no one else like him in the squad either.
He's looking great. But he's a new addition (and there are questions regarding his attitude). If I had to quickly guess how many awful games in a row it would take for one of our starters to be switched out, at least temporarily, I would say:
Gunter 2, Pearce 6, Gorkss 6, Harte 2-3, McCleary 2, Guthrie 3, Legs 3-4, McAnuff 6, Pog 5
ALF 2, Karacan 3
I imagine you want your captain to be on the high end.
