Noticed something about the AB’s defence. When they’ve got a line of say 3 tacklers, the outer one will fold around onto the Argentina side and block off the cleaners. They’ve got away with it loads and it looks innocuous because it’s not ‘tackler on the wrong side’, the player just walks around and get in the way
Barnes allowed them use every trick in the book to slow down Ireland's ruck speed. It's 'smart' play but a real pain in the ass when refs just let it happen.
