Is Roy Jones comitted enough to his Training and working on his legs?

He still has amazing hand speed, but the legs are not there where he can move and keep a opponent off balance. I know he's 41 years old but it seems his legs have been like this for a while now. Do you think he's doing the necessary workouts to get his legs in the best possible shape such as running 5 to 7 miles a day and doing sprints on the track. I recall Roy in his prime would do a lot of sprints and running his 5 miles at a fast pace. Before the Calzaghe fight they showed him jogging with the guys in the camp and the pace was extremely slow.
