I've never liked the current rules. I just think it's crazy that one offence results in three punishments, regardless of who is playing. I think there should only be one punishment on the pitch. Suspensions is a bit different, because it's needed to control repeat offenders over the course of a season. However, there's nothing to say suspension rules can't be modified either.
Before the change that Windy highlighted to me yesterday, I can remember our keeper getting sent off in a game, and conceding the penalty, followed by suspension. I just think it's bonkers, why are we punishing players twice on the pitch for one offence, sometimes fate plays against you, and whether the player intended to or not handball yesterday, there was no way he was going to avoid it, so the outcome was always going to be the same under the current rules.
