You would be hard-pressed to find too many non-Dodgers who are 27 or less and have been to the World Series twice, winning one of them. The three previous teams he's played for have all gotten at least as far as the league championship series with him.
If you want to argue there are holes in Soto's game, go ahead. Personally I'd have moved him to first base once it was clear Alonso wasn't coming back. But he's also been the toughest out in baseball since he was a teenager, and has 40-HR power to boot. Guys like that win ball games, and then win pennants, as Soto has done. The list of people (on the field, in the dugout, and upstairs) who have far more obviously let this team down these past two seasons is very long.
