The red card thing bugs me, not just our game but union as well.
IMO, there should be a 15 min period of down to 12 or 14 like a yellow then a replacement can be brought on but not the guy sent off.
Foul play should be treated differently but a lot of these cards are for bad technique or are accidental. Can make the game a non event especially if it happens early.
The perp can have a few weeks on the sideline but at least the games would be evenly matched and more of a spectacle
