It can get pretty hectic there, especially when there are multiple substitutions, and people running in and out of the restricted area. We can’t play without moving them, so the basic rule is that they go where they need to go based on the situation, and everyone else yields the right of way. I’ve seen many occasions where things are so busy in the restricted area, such as a change of possession, that the chain gang has to go out on the field to get a clear path.
