An NFL arbitrator made a landmark ruling Wednesday, saying the New Orleans Saints can pay Jimmy Graham as a tight end under the franchise tag rules and not as a wide receiver.How will this affect Vernon Davis?It won't very much, I believe. Davis, the 49ers' star tight end, is holding out because he wants a new deal. I didn't think the Graham case would have any bearing on the 49ers' dealings with Davis regardless of the ruling on the grievance.
