I'd take him over anyone on that list other than Claiborne, Coples, Ingram and Kirkpatrick. I know I'm a Tarheels fanboy, but I am just incredibly high on what Brown could do in our system.
Also, Harrison Smith belongs nowhere near any top 20 D player list, and this is coming from a big Harrison Smith fan. He's underrated, no doubt, but not THAT underrated.
Nail on the head there...
Starting LB is not as big a hole as other positions are, but man I'd love to have ZB in some pipe dream scenario. He'd start immediately over Roach, learn the ropes from 2 pro-bowlers, and take over WLB when Briggs is done. He's pretty much the IDEAL 4-3/Cover-2 OLB for our system and adds pass rush ability that Briggs doesn't have. In fact, IF (and I know this won't happen) some team wanted to trade their ZB-available pick for Briggs this year, I'd take that deal and free up millions more in cap space...especially if Briggs sulks some more about being "underpaid and unappreciated".
