I think it is important to again make clear distinctions.
Wagner struggled with the local media coverage of his performance and some fans feedback on the same. I do not recall him saying anything negative about Philadelphia the community or the Phillies organization.
Rolen's beef was almost entirely with the Phillies as an organization and how it was, in his opinion, fomenting negativity about Rolen with the fans and local media by leaking selective information (contract offer etc.) and using it as an excuse to not spend money to build a winner.
Harper has never played here and likely has little knowledge beyond what he has heard, but I still do not buy the theory that he would make this important of a decision on such a shaky foundation of information. I guess we'll see what happens, but to me if the Phillies pay him he will play here with no problem.
