Let's put this to bed once and for all.
"Jones-Drew is a 26 year old, five year veteran at the running back position. A position that perhaps wears on the body worse than any other position in sports. The wear of the position was enough to force MJD to miss the last two games of the season and have a knee surgery shortly thereafter.
While Jones-Drew certainly still has years left with the Jaguars, it's probably fair to assume he's somewhere close to about halfway done with his career with the team. He's probably at the point at which he wants to win and he wants to win now."
