I've had enough, thanks

Do England's captains do more of this falling-on-the-sword in the middle of a season, series or whatever it is, than their counterparts? I'm genuinely curious. Vaughan's decision to resign and not play in the last test speaks of a complete mental rout in addition to the cricketing one. And I suppose it was only natural that Collingwood resign as well. When the English get depressed after defeat, its contagious.
