I wouldn't discount his tagging ability. Kept bont and others to very few possessions.Forget about hard lock down, that's a waste.
He needs to play a kick behind play no matter where the ball is on the ground.
His ability to turn defence in to attack is a major weapon that is not being harvested properly at the moment.
He should be the focal point of our forward press.
Watch GR's clip again, but think about it from the perspective of a player who rolls up the ground with the midfield transition (when we get that right), rather than staying bolted down in the defensive 50:
Luke could turn 10-15 rebounds a game in to forward entries & scores, particularly now that his left foot has got it's laser guidance system back on line.
