If I thought he could do that I'd be with you. The defensive drop alone would be a huge downgrade from Billy. I'm all for getting a 4th Of who can play all three positions adequately with some offensive ability and would allow Billy to sit 30 or so times per year. That isn't Ervin IMO. The Reds have a need to fill in this area IMO.
It could be Peraza if he can develop out there but more likely they need some one from outside the organization.
