This might have been said and i just missed it, but with pretty much each one of those drafts that you listed, the person drafted in those spots has sured up a position on that team that they no longer need to address though as well. A lot of them are names that you hear now every night making plays so the value of just getting a pick that results in a playmaker like that goes a long way since u no longer have to worry about drafting that position in the next draft thus being able to draft for your entire roster, and not being stuck drafting year after year for, in our example, a DE that can actually play.
