What is the role of captain exactly these days? Is it just a label or is it an on-field leader and director of operations? If it's the former then it doesn't matter who we have since nothing much is required. If it's the latter, then Roby would be hopeless in my opinion as while he is a real presence as a player, he isn't as a person. Wello is ok but gets very frustrated at himself. We need someone who can look beyond themselves and motivate others, verbally in particular. Someone who can pick the lads up or calm them down or give them astute directions.
In a few years I could see Foster being that kind of material. He already joins in with the cajoling!
