of assistants in the booth or on the sidelines is one of those things that is never an issue unless things are going to hell. If you go back to the 1980s, Erhardt was in the booth calling the offense (Ray Handley actually acted as his conduit on the field) and Belichick would stay on the sidelines.
There was the whole controversy of Bill Sheridan calling the defense from the booth. Now, he was so terrible that they could have put him in the friggin defensive huddle on the field and CC Brown would still blow his coverage assignment.
I wonder what the overall industry standard is now related to coordinators on the field or in the booth.
I know I prefer to be in the booth than the sideline. In general, you tend to see more and see big picture what's going on. Then you can rely that information to anyone on the sideline. Being on the sideline is a cluster fuck of just activity. Sure you can talk to your position group and give pointers and feedback, but I like being upstairs.

I agree with the above comment from BigBlueDowntheShore.
Adjustments to what the D is doing are made between series using photos and conversing with another coach in the box.
There's also value in being able to communicate with the offensive players between series when the OC is on the field.
