Z and Prior aren't the only arms in the system. When you draft loads of pitchers, you use the depth to get what you want. The problem, as TheDude pointed out, is that we have been unable to develop anything between the studs(Prior, Z, Wood) and the hopefuls with potential(Cruz, Pinto, Guzman, etc.). Part of the reason is that they are unable to bring anyone in between the two extremes is that there isn't much space in the rotation to develop. When you've got 3 studs like the above, then you're already at a "disadvantage". However, knowing that you build around pitching this has to be taken into consideration. Furthermore, Hendry contradicts the overriding "draft pitching and trade for hitting" philosophy with his FA SP acquisitions, by acquiring mediocre to poor talents to fill those spots(Maddux, Rusch) instead of developing the younger players to the point where they fill the need or are valuable enough to trade elsewhere.
