High draft picks are odd things. Obviously, no player drafted in the top-10, or drafted at all, for that matter is guaranteed to go on to a long and successful career. However, there is quite a bit of pressure in drafting that high, as fans view it as compensation for a poor season or a prolonged rebuild. High draft picks are currency for the price of future success.
Philosophically, I have always been of the mind that you should always shoot for the highest possible ceiling with any draft choice. Clearly, if that upside carries an irresponsible amount of risk, that needs to be taken into account, but the general rule would be to shoot for moon.
