They were right about Grandal but that needs context too. Big difference in signing a free agent as opposed to giving up the necessary assets to trade for Realmuto. In addition, the shot at Grandal was probably before signing Cruz. They could have gotten Garver ABs at 1st, DH and catcher so adding Grandal as a free agent when they had not yet added Cruz makes sense.
Your post complained about a number of suggested FA signings, as well as trades.
And Cruz signed on Jan. 2. The Grandal offer was later in January.
