He leaves Donncha on the bench for a clearly past it Mal, and is obviously running a risk playing O'Connell who clearly isn't 100%. So, yes, he is a tosspot. Clearly the game to risk O'Connell in if you're going to take a risk is in Twickenham next week, partnered by O'Callaghan, when faced by Grewcock and Borthwick. O'Kelly and O'Callaghan should be able to handle the Scots. If not, they have no business playing 6 Nations rugby.
