"Pro Football Focus ranked Harris 18th out of 55 inside linebackers in a 3-4 base scheme last year. He has started every game (86) since Ryan took over five years ago and been terrific in run support.
Harris, however, has struggled in pass coverage. Quarterbacks had a 119.2 passer rating throwing into Harris' coverage last season. Only six linebackers allowed a worse rating."
It would appear Harris is a 2 down player at this juncture. If the Packers were to go that route Spikes might be the cheaper option.
Harris has been the anchor of the Jets defense; even with the changing of the guard you'd think they'd want to keep him.
With the age and coverage limitations he won't touch another big contract.
While it would be nice to have a Spikes or Harris for situational play...short yardage, goal line, defending Peterson and Forte, bad weather games played on the ground...the Packers have too many 2-down and situational players in the front 7 as it is.
A 3-down ILB who can lead (or grow into leadership) is the higher priority.
