I don't criticise his role as a captain - he's definitely a top lad and a top Blue - I criticise his role as a perennially limited footballer who is, on top of his limitations, now aging and should be a backup at best, really, as he's costing us more points than winning them.
Also they don't have to, but it'd be nice to stop being the good guys for about 3 seconds - imagine the team's captain getting poked and pushed in the face in the Derby, which would lead to our advantage should he actually do anything about it, but... he doesn't and just goes "oh no it's okay these things happen". Nah mate, not having that.
James (Rodriguez, not Tarkowski... yet) did it brilliantly by getting someone sent off for the smallest poke in a nothing game - imagine having an advantage against the RS for a change, instead of the exact opposite. Because that's what everyone in the league, quite literally everyone, does, but we're "the good guys™" so it's against the rules if we do it.
