Reckon you could say the same about Pagan in his time at North. Or Wayne Bennett in his time at the Broncos. Coaches that are very disciplined in their structures tend to be successful, and often end up over running sides. This has been an early trend for Voss too.
It helps when you have an absolute brilliant team. But like Lethal after 2004 and Pagan at Carlton, you can often get shown up on gameday if you don't have a few tricks up your sleeve. BTW you don't have to throw your gameplan out the window by just throwing a few people around into different positions.
