Time. Time is the fix. Kinda hard to have an instinctual Plan B, dare I say it, like the Stoems do, when you have a Plan A that is stilla work in progress in it's infancy.
The Ipswich analogy is a good one. I reviewed their game style and watched the Walker interviews a few weeks ago as I could see the similarity to the game play. One important difference is that the Ben and Shane don't believe in the importance of completions whereas Fitz does and has to as in the NRL you won't win without ownership of possession. That, and getting worked out, is why Walkerball won't work in the NRL. At least we know that as it was an interesting option at the time.
It may still work because the only way to wrest domination from Storms and Penrith, Rooster too at times is to reinvent the wheel in some way. No one will successfully emulate their styles and even if they do it's just fighting fire with fire when the opposition know how to counter.
I'm happy for the Sharks to persist with Walkerball in a hybrid state but it might take years. The right ammo isn't in place yet.
