I'd say they would do it the same way Richard did it when he built the Legion Of Boom, with mid round draft picks. The only top pick he had in Seattle was Earl Thomas, the other guys were 5th rounders and later. I'm of the believe that his faith lies in his techniques, and not having to have top draft picks.
Think about this, Byron Jones had 0 interceptions for the season last year, that's unheard of for a top cornerback. And that tells opposing offenses that the worst thing that can happen when you throw his way is an incomplete pass. That invites teams to attack him, and they increasingly did as the season progressed.
And he's going to expect to be paid like a top cornerback in his next contract, which is what? About $15 million a year? That for a guy that doesn't make plays on the ball and coming off of hip surgery? I don't put good odds on Jones being resigned, and I see these corners being brought in and kept around as proof that changes are coming.
