Then probably 99% of all play calls are failures, because you can't just call the optimal play every time.
I don't think simply because a play could succeed that it's a good play call. All plays could succeed. A Hail Mary, in theory, works every time. So no, that's not at all what I think, though it's been said multiple times. Borges called played that should succeed, that took advantage of the opponent, and set the opponent up for success. The game plan wasn't optimal, but the play calling within the game plan should have succeeded. Not could have, should have.
