I've heard about the debate on whether it is circulation or the pressure difference that causes lift. I've never heard it argued that mechanical deflection is the cause for lift in subsonic flight. In my mind (and I've read this, too), circulation causes the pressure difference which in turn causes lift. Think of a baseball thrown with a spin. In that case, the lift generated is purely by circulation. Same thing with a cambered airfoil.
