If you don't have the ball. Tackle the person with the ball. It's not rocket science.
I don't mind the 'less tackling style' when we control possession and can cover heaps of ground with long precise kicking. But if you don't have ball in hand you have to tackle. it's unforgivable that Chaplin, Batchelor, and Grimes laid no tackles considering how many times the ball ended up in our D50
