This rule change only applies inside the penalty area. As it says, they decided the triple punishment was too much- PK plus RC plus suspension. So inside the box, DOGSO becomes a YC plus PK unless it’s blatant. Neither incident last night was inside the pen box so regular DOGSO rules apply.
The difference, whether you agree or not, is there were 3 other defenders- behind yes but close to Maxi and they were all faster than him so we was never going to be 1 on 1 with the GK . The Portland foul was isolated with no other defenders in a position to catch up.
