I don't know, but I think I was the first here to bring up Smith.
Richard Seymour (Raiders) is in a similar situation. There are parallels: DE, division rival, probably something in the tank for a year or two. Likely to sign with a contender. As I said before, I wouldn't be shocked to see the Broncos bring him in for a looksee.
But the difference this year is that DE probably isn't the biggest need of the defense. Defensive Tackle, Inside LB and Safety all look like bigger issues, especially ILB.
