Ross Lyon invented the McDonalds of football. Systems based, no skill required. Where McDonald's only requires 14 year old pimply faced kids to pump out enough marginally edible food to be successful, in Ross' world, a simplified, systems-based approach doesn't/shouldn't require elite players to make it work. In Ross' world you stand in a certain place depending on all the variables at play (where the ball is, are you in defence or attack and the myriad of other things they would train), and when you get the ball in position X you kick it to position Y. Usually just in the vicinity of position Y, hence no actual elite kicking required. His game plan is the epitome of using role players in every position, but if you happen to have a Pavlich of Fyfe in your team, that is a bonus.
The thing is, it works to a large degree, except that Ross doesn't also run the AFL who get to change the rules as they see fit, and as others have suggested the limiting of rotations hurt his plan and he couldn't/wouldnt adapt. If a gourmet burger joint happens to move next door (Hawthorn 2012-2015) you might be able to compete, but you'll always be dishing up second rate stodge. And now Ross is gone, and McDonalds is serving SALAD.
