While the 21-year-old is viewed as a potential star of Irish rugby, he crumbled on his biggest match to date when Ulster were routed 42-14 by Leinster in their European final at Twickenham in May. But from his vantage point in the opposing midfield that day, O'Driscoll saw enough to conclude that the negative appraisals of Jackson were unjustified.
"I heard Paddy talking about the learning curve from the Heineken Cup final," said the Lions centre.
"In fact, I think some of the stuff written about him in that game was very harsh. He really didn't have that off a game. There were a couple of skewed kicks, but that was the extent of it. He did the fundamental things like tackling well. He passes the ball nicely and takes it to the line.
"He was an easy out for people. Not that he got scapegoated, but some of the pressure put on him and things written about him were unfair. And that's coming from someone who was playing against him.
"That was eight months ago and you've seen his performances throughout the year. It certainly hasn't affected him in any way, shape or form and he deserves his opportunity.
"He's said he's learned a huge amount from that and has come back and shown a great ability to play what he sees in front of him. That's an exciting aspect to his game - he's a heads-up footballer and isn't afraid of having a go himself."
Jackson will be joined in Ireland's newly configured backline by another 21-year-old uncapped Ulsterman in Luke Marshall, who has replaced the injured Gordon D'Arcy. The duo excelled during the non-cap international against Fiji last autumn, but will be gifted far less space at Murrayfield and their selection is a bold move by head coach Declan Kidney.
"The proof will be in the pudding when they get out there, but they're confident guys," the 34-year-old O'Driscoll said. "I certainly don't envisage either of them freezing. They've played in big games. They're going to be big game players and lots of players have been dropped into the deep end of Six Nations rugby and survived.
"I'd imagine they'll survive as well with no problems whatsoever."
