Richie Gray (Scotland)
Gray has made a name for himself as an animal in the maul and nuisance in the lineout. He towers over most of his peers at 6ft 10ins and his natural height, combined with hitting the scales at almost 20 stone, makes him a formidable foe for any player.
George North (Wales)
Another back known for bulldozing his way through defences, North has made his name by being monstrously strong. His sheer strength was most notably demonstrated on the 2013 Lions tour to Australia when he picked up Israel Folau and carried him… while the ball was in his hand!
