I think you can get Kennedy without Sanchez/Norris. San Diego got him for basically bullpen pieces. I think something like Ian Kennedy and Chris Denorfia for Sean Nolin, Mitch Nay and Kevin Pillar would be fair for both teams. Sean Nolin would be a cheap/controllable replacement that should be able to stick in the NL and a pitcher friendly park. Mitch Nay is a nice prospect and Pillar could take over for Denorfia as a guy who can hit LHP and can play all three OF spots.
