These kind of studies are somewhat mathematically flawed in one distinct way
(as years of reading Bill James will tell me).
 
Good offensive teams win games by wider margins  i.e.  8-4, 6-3, etc...
Defensive teams win games 3-2, 2-0, 4-2.
 
The latter is no less effective, but in doing analysis based on total goals, it
skewers things.  It's possible to correct for this.  I'm not sure if Robin did.
 If so, I apologize.
 
Just wanted to put that on the table.
