Continuing on in our World XV series, this time we name our six best locks in rugby right now and get you to vote.
Second rows are considered the engine room of rugby scrums; they are traditionally the hard men of most teams and very often make great leaders, as we see from our selection below.
They need to be big, powerful men, able to lead the physical confrontations and also to offer an option in the lineout.
You can skip to the poll HERE or scroll through the contenders before making an informed decision.
Here are our nominees:
1. Eben Etzebeth – South Africa

6ft 8in and 18st 5lbs, the abrasive 25-year-old is a big scrummager and powerful ball carrier, who has a knack of making serious dents in opposition defences.
Reliable in the lineout with a big engine, Etzebeth has been compared to the Boks legendary enforcer – Bakkies Botha.
Expect the 58 times capped powerhouse to be at the heart of the South Africa boilerhouse for many years to come.
