[just another ref]

I am not unsympathetic to the lady coach, but we have some sidelines around here that simply will not accommodate a wheelchair. It's a matter of physics.

As for the main issue, why does anybody have to "utilize the box?"
I can't see having both of them in it. She asked how many timeouts she had left and they gave the answer to her husband. This is a big problem?

Sounds like much ado about very little to me.
