Yes - and I think the Phils would answer the same way. The Realmuto deal wasn't part of some pre-planned strategy that assumed Machado/Harper. The Phils have had interest in Realmuto for a while, but he wasn't considered available. When he became available, they moved to acquire him.
If you define their overall strategy as "get better," then identifying Realmuto as desirable, and acting to get him when the Marlins made him available, was part of that strategy. Pursuing Machado/Harper is also part of that strategy. But I would like to think that the strategic approach has been developed to not be dependent on every pursuit of improvement being successful - because almost by definition, they're not all going to be successful.
I guess that's why I'm not particularly interested in helping the Dodgers by taking Pollock off their hands. He's not good enough to be a significant improvement...and the Phils already made a better move this winter to improve the outfield, in signing Andrew McCutchen, who is only one year older than Pollock.
