Quote Haywire="Haywire"Exactly, particularly the second point. Almost impossible to fend somebody directly from behind - if they are quicker than you all they need to do is to get right up to you and grab your collar for an ugly but effective tacking method. Running away brings the hand off into play and gives the ball carrier (if the ball is in the correct hand) another option when the defender gets within range, its probably much easier too to judge the Martin Offiah style hitch kick if the defender dives for your legs from an angle, rather than directly behind.'"
I is all about shifting the trajectory of your momentum in order to evade being tackled. Action from one player will always be quicker than reaction from another.
Broughy is the one who decides to "shift" and in doing so he gains a split second advantage over Tadulala which translates in to a greater distance between ball carrier and defender.
There are many occasions when you will see an attacking player shift trajectory a number of times which has the effect of completely throwing the defender off track.
