In the long run this has more to do with the money Reggie wants.
If he takes a decent contract for 2-3 years then he will remain with the team and work with RB committe. I wouldn't be opposed to seeing Reggie, Miller and Thomas split carries depending on the game plan and situational play. Reggie is our best receiving RB out of the backfield and can also be utilized as a WR which adds to his value. Not to mention at this point and time is basically our biggest "homerun" threat on the field.
Regardless of the dancing which even frustrates me, when Reggie has one of those "days" he is near unstoppable.
