Lynn has had a stint with the Jaguars before, as the running backs coach from 2003-2004 under Del Rio. Under Lynn, Fred Taylor ran for 1,572 yards as the Jaguars had one of their top 4 rushing offenses in team history. In 2013, Lynn also helped current Jaguars running back Chris Ivory amass a team leading 833 yards on 182 carries.
It's a bit surprising to hear Lynn's name, especially after rumors about a Lynn-Bradley ticket. If he's is hired, then I'm almost positive that Gus Bradley will not be his defensive coordinator.
This may be the Jaguars doing their due diligence, as the front runners for the job still appear to be Kyle Shanahan and Mike Smith. However, it's good to see them doing their homework and looking at as many candidates as possible.
