So you concede that pressure on the kicker is not an important part of defending?
You would rather us stand back and give JT, Reynolds, DCE and co time to do whatever they want with the ball?
Well, I might be saying that. Or I might be saying that pressuring the kicker is not the kind of thing that it needs a top-paid, rep-level back rower to do. I mean, if Farah spent every training session carrying bottles of water to and from the sheds, and I then suggested this might not be an adequate use of his talents, would you then say "What do you want the players to do? Die of thirst?"
Ignoring the blatant embellishment and irrelevance of your example, it is an aspect he brings to his game in addition to other more subtle elements he brings onto the field.
If you want to compare him to equivalent salaries that's fine. Unfortunately the Tigers ability to scout and poach players has been so poor that if we were to get a Watmough, Burgess etc we would have had to have paid 900k to attract them and then we would all be blowing up that they weren't giving us 900k of service.
