Oh okay I see, then this is just a semantics issue
To me cage control and footwork are synonymous because range and pressure are just aspects of footwork along with movement. To me footwork is just effectively positioning yourself to maximize your offense while hopefully minimizing your opponents.
For example, Jose Aldo has far better footwork than Franke Edgar, but my assumption is that you'd probably argue that Frankie has better footwork but Aldo has better cage control (that might not be true, but you gather from my example where the difference lies)
carry on, I was just curious
