After two rounds of action in the 2017 RBS 6 Nations, competition for places on the plane to New Zealand could not be more intense

And in the second row potential British & Irish Lions are putting up their hands for selection left, right and centre.

Head Coach Warren Gatland has much to ponder – indeed two-time Lion Scott Hastings believes it is the most competitive position in the entire squad.

LionsWatch is taking a closer to look at the potential competitors for each position before Gatland names his squad on April 19.

Having run the rule over tight-head props, wingers and scrum-halves, here we look at the locks.

LEADING THE LINEOUT

To get a better idea of what a Lions lock looks like – who better to ask than Gatland himself.

In a video for principal partner Standard Life Investments, the Head Coach said: “For the second row, firstly it is about the lineout and their ability to win the ball there. And also to compete on opposition ball – that is number one.”
