Here, RUCK picks out the giants of world rugby.
Six Nations beasts:
1. Andrew Porter – Ireland
Lions contender Porter is poised to make a sizeable impact for Ireland moving forward. The 25-year-old Leinster tighthead, who has won 32 caps, is a huge carrier, massive in the scrum and is renowned for his freakish ability in the gym.
According to Jonny Waterson in The Irish Times: “Noted for his strength, Porter, if the figure doing the rounds is accurate, can squat 350kg (772lb) or, if you like, three Cian Healys. Quite an effective mass of cleaning-out power.”
