you know, i always thought of this as a really good idea, and yes sometimes it works, but i find it much safer, and often more effective, if you get your best tackler and follow the ball. reason being? if you tackle the 5/8 then you never know where the ball is actually going to go. instead of the centre passing it back to the 5/8, he will run it instead, and make massive meters. wheres if you let a play wrok, and then have your tackler right there for when the last player gets the ball, and smash him then they often dont make any meters!
