Last night I saw a player get grabbed from behind and thrown on the ground after the whistle had been blown. All that was given was a yellow card warning. Then the same player who threw him on the ground smacked another player in the face directly after he got the first card. Nothing was done by the ref. Makes me sad. I think the issue of enforcing the rules on the field needs to be addressed as well. Then again, we complain enough about the refs already. I just needed to vent.
But as far as suspensions go. There are already rules in place but it seems like a straight red for a wild tackle shouldn't be held on the same level as a punch to the face as it often is.
