You keep saying this. You have no evidence that this is the case. You have not been in the discussions and are reading into tweets from various sources many of which are either not reliable or are mouth pieces for agents.
For all we know Harper has a price and the Phillies have not yet met it. If that is the case why should he sign for us? Even if its the highest number? Maybe he and Boras think it may be worth their while to sign a shorter deal for a higher AAV if they can't get the ten year deal they think Harper deserves. Or they may only be engaging with the Dodgers and Giants in an effort to encourage the Phillies to increase their offer. They are perfectly entitled to do so.
I'm very excited about the moves the Phillies have made so far, but in my mind at least they made those moves as part of a strategy that involved adding Harper or Machado or a similar level player. Moving from ~80 wins to ~85 wins isn't worth what they gave up. An 85 win may be more fun than an 80 win season but the outcome is roughly the same. You miss the playoffs.
Trading for Realmuto only makes sense in the context of a team who was 2-3 wins away from winning the division. Otherwise the risk in giving up Sixto is not worth finishing 3rd in the division and missing the playoffs. Similarly with the Segura trade. Giving up Crawford as part of a deal to get Segura made sense. Crawford will hopefully one day become Segura but we want to win today so we give up the future value of Crawford for the present day value of Segura. Why do that for a team that doesn't plan to compete to win the division?
You may say that we already have enough to compete for the division but you are basing that on hope and not on reality. Unless we see huge development from the likes of Williams, Franco, Kingery etc then this team is not currently constructed to win 90 games.
