Sounds like he does intend to play. We have the inside track on this given his home, connection to Kollar and our use of the 4-3. All the 3-4 teams (including Dallas) will be out of the running. My guess is he'll give us the last shot to match any offer he gets elsewhere.
The competition for his services will probably be Atlanta, New Orleans and/or Tennessee. All could use a DE with his pass-rush skills (what 4-3 team couldn't?), and it sounds like he doesn't want to be a long way from home. But, again, nobody can match our geography.
If I'm Rick Smith, I'd offer a one year deal with two tiers keyed to the number of snaps he gets. The lower tier applies if, as expected, he's used purely as a pass rush specialist. If injuries force him into an every down role, then he gets into the higher tier. Make sure he'd be happy at the lower tier (so that he won't be upset if he doesn't get enough snaps) and that he understands that the higher tier is there solely to protect him from giving us the windfall of getting every down production in exchange for a specialist's pay.
But make every effort to sign this man. He's absolutely a guy who can help us.
