Said it before but....
JFH is not anywhere near as good at line bending as AFB (I didn't say that so much, lots of others have, I do not disagree).
But the point of having JFH in our pack is that he and
Barnett + Ford and Leka are fast props.
All those blokes have fast leg speed coz they're not big and heavy. They can maintain that leg speed longer than heavier props. So while they may not bend the line as much, or drag the tacklers along further....what they do achieve, is less time to rest for the defensive line before contact.
Each one of our props on his own barely makes a dent in the oppositions energy reserves on his own, the effect of their leg speed is minimal on individual defenders in individual tackles (AFB types on the other hand tax the tacklers a lot with one run) but our fast prop model speeds up our game which collectively burns out the entire opposition line - rather than just one section in the line based off big impacts.
Therefore it is vital for our style of game plan that we keep the ball in play as long as possible and use our fast props to run the opposition to death.
It is also important that the fittest of our fast props (obviously
Barnett and JFH) play as long as possible because they are eighty minute options and therefore we need to keep their base fitness high for that contingency in games where we are forced to have them run the whole game.
As for Wiz worrying about more running and more contact = more risk of injury....you cannot take that negative mindset into contact sports - and where coaches and players worried about potential injury....teams like the Storm, and players like Cameron Smith would never have evolved.
The Warriors are achieving (ugly) wins atm because quite simply the opposition are tanking after having to run back ten meters quickly for eighty minutes more than anything.....
