Tackles to me merely determines how hard you work when you don't have the ball.
Even perceived pressure can cause errors if you are a good tackling side.
Although we are improving I would like to see more pressure on the opposition when they have the ball. Too many times I see us make mistakes and the fwd entry 50 on the rebound against us is clinical or we seem to get carved up easily just through the game at times when the opposition have the ball.
Having said that I feel the last two weeks we have missed Foley's in and under grunt, his pace and ability to break the lines and his tackling pressure on opponents. His absence has made us look alot slower and we have missed his presence more than we care to realise.
