but rugby TMOs also have a bank of screens ..... don't they ?
They may well have, I don't know. However they seem to concentrate on showing each angle at a different time, at least to the refs/fans. Based on the BBC, there are 4 refs in the VAR room, and there is supposed to be a feed to the ref on a pitch-side screen, but I have not seen them use that in the few games I have watched. VAR was used in the FA Cup last year, I believe.
