I was at the Ticats/Al's game. There were several penalties called where you could tell the head ref was in communication with the Command centre before calling the penalty in the stadium.
If there is a penalty called on the field announce it. If Command wants to change it, let us know after the call on the field.
Late in the game, there was a flag during the play. About ten seconds after the play, during a scrum there was a late flag.
Again you could tell the ref was talking to Command. After a long conference, they called illegal block on Hamilton. That was it. No reference what the late flag was for.
Until there is transparency with communication between the refs and the Command centre, betting will never be serious with the CFL.
