However from the point of view of the RB position.
1. Could he carry the ball 25+ a game - yes
2. Was be a breakaway threat? - yes
3. Was he durable - yes
4. Could he catch - yes
5. Could he block - yes
6. Was "Wad" ball a motivation for wanting to quit - Yes
7. Could he pass a drug test? - no
If he could prove his demons are in the past would I be willing to give him a second chance? - yes
