Prop Cian Healy is expected to miss the start of the 2014 RBS 6 Nations after undergoing surgery on his injured ankle on Wednesday.
The 28-year-old Munster man kicked 20 successful place-kicks throughout the Championship - 14 penalties and 6 conversions - as well as two drop goals against England, for a five-game haul of 60 points.
Wales' Stephen Jones, O'Gara's closest rival and perhaps biggest challenger for a Lions' Test team spot this June, depending on the fitness of England's Jonny Wilkinson - had 22 successes for a 57-point return.
O'Gara admitted in the aftermath of the 32-20 loss to the Dragons: "The charge-down try was a killer. I didn't see him (Gethin Jenkins) and that made it 10-3 - after we had started the game well.
"We were chasing them from then on, but every time we got into a good position we gave away a penalty. We were penalised for indiscretions that baffled us a bit - but the better team won on the day."
Ireland's David Humphreys - who kicked three conversions from three in the tournament, two against the Welsh - had a 100% return for the 5 minutes he saw at Murrayfield and Cardiff's half-hour effort.
