Ireland led 13-9 at half time and although they started the second half in serious fashion and despite the fact that the Scots were reduced to 14 within a minute of the restart when Nathan Hines was yellow-carded, they never managed to impose themselves a their pre match odds of 1/7 might have suggested they might.
In fact they were behind 18-16 with just ten minutes to go before O'Gara kicked them into the lead and if one considers that Denis Hickie, made two try-saving tackles they may count themselves lucky although nonetheless totally deserving to be celebrating that third Triple Crown.
