As we as a site have pointed out at length, specifically back at the trade deadline, the case for trading Gore is a very simple one to comprehend. He is a Scott Boras client, who is notorious for not having his players sign extensions before going to free agency, and the Nationals don't seem close to competing with him before he hits free agency after the 2027 season.
"Ohtani isn't one of Boras' clients, though not for lack of trying. Before Ohtani came to the US in 2018, Boras flew to Japan five times and met his parents in an effort to land him, only to lose out to CAA's Nez Balelo."
