I might be missing something, but the style of game and team selection I am seeing from teams such as the Bulldogs is speed, power, athleticism, explosive ball running etc from their edges and mostly workers in the middle.
The interesting thing with Panthers and Bulldogs is they compress and are relentless in the middle which then limits field position and points against them but then provides 3-4 chances to convert and win games.
Storm, Roosters and Dolphins are different again as they have a more speed/dynamic style of game plan.
