Their bats are legitimately excellent though, they're currently the 7th best offense in the league. However, they combine this with horrific defense (3rd worst) which makes their position player group as a whole only a mediocre 14th best in WAR.
The pitching staff is genuinely horrific though, I think people expected a bit more out of it since they spent money on acquiring Severino and Springs, with some mediocre incumbents like Mitch Spence and JP Sears and one of the better relief arms in the game in Mason Miller, but the wheels have totally fallen off on them. Severino has been fine, but everyone else has been a disappointment across the board.
