As reported by the Charlotte Observer:

Carolina Panthers' coach Ron Rivera is popular at Senior Bowl | CharlotteObserver.com

The Panthers met with Bill Davis on Monday about the linebackers position, a league source said. Davis coached outside linebackers under Dom Capers during the Panthers' first four seasons of existence. Davis, who has been a defensive coordinator in Arizona and San Francisco, spent the past two seasons in Cleveland. Jacksonville linebackers coach Mark Duffner interviewed with the Panthers last week before deciding to stay with the Jaguars under new coach Gus Bradley.

I think I'm seeing a trend in some of the potential new hires. Rivera seems to be leaning on experience over youth or potential for those candidates he might bring in from the outside. I would assume he is done promoting from within though I wonder is Sam Mills Jr might get a shot at the LB coaching spot. Of course I might just be assuming Mills knows something about LBers given his father was an outstanding one but that could be a very misguided reach.

Davis is another experienced guy who has history in Carolina and would represent an 'experience' pick over potential. Since Capers ran a 3-4 I would assume Davis has experience in both formations, the 3-4 and of course the 4-3.
