They are already covered by Rotham, Duggan, Nelson and Cole. Professional clubs don't wait until a player retires before they replace them. That's how some people on here think (or actually don't think).
Johnson won't play much next year, he and Foley are 2 - 3 years development away from grabbing a regular game. So they will be more of a Sheppard replacement when he hits 31+ and these kids hit 21 - 22.
And which one of these players even remotely demonstrates the offensive kicking skills of Jetta and Hurn?
I'm not saying "Oh gee we have no half backs", that's bullshit, we have plenty. But what half backs do we have that are creative and attacking by foot?
The discussion was originally about how much better our team looked in 2018, and how it was stemmed from our silky rebound from defense.
