Some players, particularly forwards, lose their x factor and never perform as well.It is not just a age thing . Due to the toughness of the game most players can only have so many injuries & hits before they lose that little bit extra effort that got them there in the first place.Add to that whilst sitting on a very nice contract that sets them up for life and the stimulus to perform is not what it used to be. We have seen this with Vaughan & Simms ( and to a lesser extent Frizzell ) and they don't intimidate opposing sides like they used to.
Young players have got a lot to aspire to such as representative games & big money contracts. They are driven to achieve this, so just go out there and just rip & tear. You will only see it in true champions like Tulomolo that can sustain high performance over a long period of their career's. Sure , a former champion at discounted rates provides experience and a big body , but with too many in a side you get the Dragons ! A long way of saying no to Napa but we need forwards without too much mileage under the belt and fire still in their bodies & hearts.
