I don't think the CSAF has as much power to change the AF as people think he has.
Quite a bit of what we see as "bureaucratic crap" is actually the execution of some federal law. For example, awesome queep job of Unit Voting Monitor is actually the AF and DoD's implementation of The Uniformed and Overseas Citizens Absentee Voting Act.
On top of that, the CSAF will get to go battle Congress every time he wants to erase a GO billet or move an airplane to a different base. As an example, a developmental squadron I was in had two A-10s dedicated to A-10 developmental test. To increase test efficiency, we wanted to move those airplanes to Davis Monthan where there are quite a few more aircraft in the test fleet. That move was blocked by Congress as "trying to move aircraft outside of a BRAC."
My one critique is that I wish Gen Welsh would do more to shape the Air Force culture. We still have the same rusty OPR and assignment system. We're still deploying dudes into "rated-required" billets where being rated isn't actually a criteria. We're still trying to accomplish all the same manpower intensive work as if we had a force 50% bigger than we actually have.
