Well, there are many factors that decide how to pick them. If you always pick the best available player, that won't work either. What if the best available player was a running back? Do we need to pay two RBs that big of money? especially when we have jackson as well? What if we drafted a Rb in the first round, then when we drafted in 2nd round the best available player is an RB? and the same happens happens in round three where the best available is an RB? You get three RBs that you don't need. When people say "draft the best available" there is always wiggle room. And yes, you do draft need sometimes. If you don't, you will fail. What if you team has no QB, but every time you pick the best player available is never a QB? you are going to have to compermise to get a QB, because you need a QB. If you need a position, you better draft it at some point. You can pick all the "best available" you want, but if you are missing a position, your team can't play.
