That's largely because 3.x didn't have a robust mathematical "spine" like 4e did, instead relying on its class/level system to try and build monsters in PC-like fashions.

On the other hand, I could throw a high Strength, Natural Armor, or Con at a 3e monster, have it mess up balance, and leave the CR unaffected.
