You don't save much and that's another edge rusher you have to replace. We already are missing one, why save 3 million to miss both? Floyd is solid at times and would probably benefit from a quality rusher on the other side.
You can upgrade positions without making more holes that you have to fill. Especially if it doesn't make cap sense. Same thing with Robinson. You don't save a lot, I don't think so unless you have a better option it might be better to keep him another season.
