#4. Brian O’Driscoll (Lions)
The New Zealander was asked about the most impressive player he has coached during his time with the Lions.
“I saw him in 2009, having given him his first cap as a youngster coaching Ireland. I was unbelievably impressed with his development over eight or nine years and how mature he was, and how much he understood the game.
“He was sensational in terms of his rugby understanding and rugby knowledge. The way he prepared and approached. He’s probably the best players I’ve coached from a Lions perspective.”
