Like "patriotism being the last refuge of the scoundrel", so is "leadership" the last refuge of the useless footballer, if you have two players that deliver the same results or so close they can't be separated then play the "leadership" card, but when there's a gap in output just select the better player, the less injured player.I call bullshit, we didn't miss Brown's unquantifiable "leadership" or "rallying" yesterday at all.
The other side of the leadership coin, if the "leadership" player, can't run or kick or tackle has to hide in the forward pocket, then all he has to offer is telling other people what to do and he'd have to be a genius at that to make up for his limitations, if he's not that genius then he's just pulling down his team mates that have to work that much harder to compensate for his limitations, which over multiple weeks and months creates resentment and cliques within the playing group.
It also becomes a crutch/false dichotomy to select on field leaders when there are issues with off field leadership.
