The second row forwards (also known as locks) are the engine room of the scrum and the target men in the lineout, meaning that they need to be tall, powerful players with excellent scrummaging technique and pinpoint timing.
If they bind to each other and the props too loosely in the scrum their pack will lose power, and if they are not accurate and dynamic with their lineout jumping, it offers the opposition forwards a chance to steal possession.
In open play the second row’s duties have evolved from being support players at rucks and mauls to ball carriers. If a marauding second row is comfortable with the ball in hand, their bulk and power makes them very difficult to stop.
Strength, jumping, good scrummaging technique, confidence with the ball in hand
