6 would be the low end.
6-7.5, maybe 8 depending on the team.
as you said, best backup, and a more than capable starter. I can see teams giving him something in that range for 3 or so years
Most of the NBA teams now have an established starter better than Jose at the position, or have a young player being groomed to be the starter where they wouldnt sign an aging vet to take his spot. Theres no way he gets over 6 million, as there arent enough starting positions available league wide and no one is going to sign him for that much to be a backup as Jeff said
