Which is why I mentioned personnel department and coaches. They've drafted a ridiculously deep team right now, and there isn't much out there that says they can't continue to do so. Plenty of teams like the Ravens, Pats and Steelers have consistently drafted well throughout the years and were able to replace some talent when it was time for them to leave.
Hard to say they'll continue to draft as well as they have. They have had some late round gems come out and start for them.
