Quote: moto748 "I'd go along with that summary, but surely the point is it's by no means restricted to Wigan. Could you not argue that many (most?) SL and NRL sides adopt a similar policy, with split halves ands a full-back helping link the play. Of course, what the rest of them don't have is Lockers. On the other hand, many of them offer more variety from dummy-half than we do.'"
I'd say most follow the structure but operate differently.
For example we opt for our props to find their feet, quick play the ball then dummy half out with quick distribution to the halves. Other teams like a 9 who is given the opportunity to run, scoot from dummy half if they chose or even jump from dummy half into a first receiver position, then start the play from there.
Roby, Clark etc are allowed to scoot when they see fit, Rob Burrow was fantastic at quickly scooting, almost sideways into a first receiver position allowing for the whole attacking line to move on one, subtle differences can be the difference in starting the play.
Other teams like their props to 'hit and spin' looking for the offload, others allow their props to push for yardage after contact, there's pros and cons to the subtle differences in how you employ tactics.
Others chose to use the 13 as a straight up 3rd prop, this nulls a ball playing link like Lockers, but does allow for the starting props to remain in the pitch for longer, as the drives, workload is split by 3 not 2 props.
There's so much to it, the structure is merely the foundations.
But playing Sam anywhere other than FB? crazy.
