I don't there's nearly as much in it as some are making out.
For lack of specific parameters, I could only really assume every player is at the peak of their powers as known to date (i.e. not extrapolating with the younger chaps).
Top liners/elite/A-graders/etc

The retirees clearly have more top liners, but I think the current mob catch them up for overall numbers when you include the next line. Not a recipe for a 10 goal hiding IMO. In fact if Bundy and Motlop were included, I'd be willing to call it even.
