The Phillies were able to bring in two borderline HoF players from outside the org on deals that have worked out better than even they could have hoped, in Wheeler and Realmuto. Two of the best acquisitions of the last decade, for any team. Jury still out on a bunch of the others, though Harper has earned his pay so far.
Wheeler actually leads the majors in fWAR since his signing, and the contract expires after 2024, so not much can go wrong. Legit one of the best FA pitcher signings ever.
