rods as a sole ground haven't been in the code for some years now.  Just 
like using a water pipe isn't permitted as the sole ground.  (they can 
be "part" of a grounding system)

I think the rod thing is because, when all is said and done,a single rod 
is terrible ground connection, and its performance is very, very 
installation dependent.

Compared to something like a Ufer ground, especially.  It's hard to beat 
  tons of concrete with tens of square feet of contact area with less 
than a fifth of a square foot of contact area in a rod.
