It's not just that way in the football draft. Good organizations of most any kind make decisions based on a menu of choices and an "if, then" matrix because an organization doesn't have control of every aspect of that menu.
But especially in the NFL draft, where the choices and "if,thens" are actually somewhat, but not entirely, within a range of predictability, then to prepare you must spend much time going through as many of the most likely scenarios....and a few less likely.... if for no other reason than to prepare yourself to be able to react pretty quickly and with the best decision/choice possible.
In the end, these choices amount to a batting average, knowing a percentage will succeed and another percentage will fail. Just like all decisions in life. It's a matter of having the best info you can get, good decision makers who also can include an intuitional sixth sense, and pulling everyone through the knot hole to get there.
