No, but he comes from a successful family tree...with lots of recent success. Our guys did not do anything of note in Anaheim or Baltimore, though they helped build the latter in the same way Wade helped build the Phillies.
The Mets also failed to hire Bloom. It worked out very well for him because he got to run Tampa for a while and get the President's job instead of the GM job when he finally went to Boston. Of course Boston is a mess at the ownership level too. But at least they managed to win during their mess.
Unfortunately I don't think signing or not signing Realmuto is really that big an issue. I guess I'd say that if the only reason they didn't sign them is because they didn't want to pay the tax, and failed to construct a roster that allowed room to sign him, that's a pretty big failure. But it was reasonable at the time to think that they could strike a deal to be announced on Opening Day. The virus changed all that.
If you think this team is not in especially good shape, and is hamstrung by contracts, without much talent in the pipeline, why would you want to sign a 30 year-old catcher to a four-year deal, let alone a five or six-year deal? At this point you only go all-out to sign him if you still think you can win division titles in the next two seasons.
And I'm less worried about Harper demanding a trade as I am that it might be better for the Phillies to get him to accept one. Again, if this team is only a marginal wild card contender at best for the next two seasons, they'll have wasted Harper's prime.
I'm not prepared to hold a funeral for this season, the team is pretty good but for the bullpen. Or the next two: they'll have money to spend next year with Arrieta and Robertson gone (even more so if they don't sign JT). But if Cutch and Segura remain in decline and with 1B, 2B, and CF still in question, plus nobody ready to just step into LF or SS, there are more holes than there are ways to fill them.
