Quote: LocalSuperhero "Yeah I've heard that argument before and I recognise that their are times for that, but the amount of times and situations Webb chooses this option suggest to me he would just rather not make the tackle. Back pedalling does not really pressure a player into making a decision it just gives him time to make a more informed decision. I'd be more inclined to go with hit him as hard as you can as soon as the option presents itself. Worked really well for JPR Williams, who i regard as the best defensive full back in the history of either code.'"
Well its not that simple though. Firstly, going into hit him as hard as you can is more likely to result in you missing it, as your footwork is less likely to be up to scratch, than if you wait for the right moment and bring him down. Also, fullbacks are not generally the biggest and best tacklers, so going for a smash would more quite likely to result in being bumped off.
Also, with a player 1 on 1 with the fullback, if he's brought down quickly there's a pretty high chance that the supporting players will score from the next play as the rest of the defensive line are not back onside. Again, if you try and slow the runner down, and make them make a decision, then it also allows your players to get back, and be better positioned for the next play.
