Red Dragon was always going to be one way, as a lander for some notional science payload. It was still a bit harebrained because it wasn't clear how to deploy that payload, whether rover or other, through the hatch. (I think I once saw a slide that had a subsurface drill deployed from inside the capsule by drilling through the heat shield.)
