The Jaguars released the 31 year old because they did not want to pay him the five million he was scheduled to receive this year.
John Henderson was signed to a one year deal in June. The former Jaguar will be a key piece in fixing the run stopping issues that have plagued the Raiders for years.
It has been disputed if the two time pro bowler's tank is near empty. Jerry McDonald of the Oakland Tribune had one source tell him, that Henderson was "done."
It has been well documented that he is no longer a factor against the pass. But he remains a very stout run defender, and may bring some versatility if the Raiders play him at nose in the 34 scheme.
We can all expect that Henderson will not be half-assing it because he will be playing for a long term contract.
