No, in large part because of the pitching results they've gotten. Those "one-game guys" haven't been the problem, they've merely been the patchwork filling in holes because the likes of Senga and Manaea, and Megill, and Montas, and Blackburn, and Minter, and Canning, and Nunez, and (more recently) Helsley, have all been injured and/or FAR below expectations. You're mixing up cause and effect here.
