Sorry bull boy 2011, tackle legs first at super league level and all that will happen is offload after offload. What does need to happen is the initial hit wraps and split second later legs taken , followed by a 3rd who then controls the speed. A 3 man tackle is so more effective than a 1 man 'smash' tackle!!!! This is the reason a average giants side compete as they do this very well.
Our defensive problem is 1- some of our players are by far the worst in the league at reading attack , 2- Not all the players are aggressive enough in defence , and 3- Our fitness is dyer

but correct about line speed, ours is terrible

Judging by the picture Potter should be used to working with empty vessels... Although he seems to have some difficulty in getting the team fired-up this season. I think it is time for him to change the temper and make-up of the side but he has to be careful not to act like a Bull in a china shop.

...and that's putting a gloss on things.
