Linebackers coach Mark Duffner liked living in Jacksonville and working for head coach Gus Bradley and the Jaguars, but the opportunity to work with an old friend was something he couldn't pass up.
That's the reason he decided on Sunday evening to join the Miami Dolphins' coaching staff, where he will be reunited with Dolphins head coach Joe Philbin, with whom he worked in Green Bay, writes Ryan O'Halloran of the Florida Times-Union.
Duffner was hired by Jack Del Rio in 2006 and was retained by Mike Mularkey in 2012 and Bradley when he was hired in January 2013.
"The guy gave me a chance when nobody else would," said Jaguars linebacker Russell Allen, an undrafted free agent who has started 44 games -- including five as a rookie in 2009. "... I ended up playing quite a bit as a rookie because of what he taught me."
