I like your analysis on rim protection, but I would take it a step further.
Rim protection is about protecting the rim and the area around it, the same way that a wall protects a city or an army defends a castle. You’re not just protecting the rim - you’re protecting the area around it.
In the NBA, they have the “restricted area” where you cannot draw a charge. That space represents the most important 3 feet on a basketball court. If you win those three feet, you control the layups, the rebounds and the pace of the game. If you do not control those three feet, well, good luck trying to win.
You have to be able to protect those three feet. The easiest way is with an athletic big along the lines of Patrick Ewing. That makes things really easy because you can protect the rim with one guy.
If you don’t have that, though, you can do so strategically through positioning and sound defensive rotations. This method is harder because if one guy is out of place or late, the rim is left woefully unprotected.
