You also "ruin" their family's plans that weekend because the dad is in jail and can't drive his kids to Lake powell. Except it's not the person enforcing the penalty who "ruined" things. It is the person who couldn't control their behavior and violated the rules. The NBA isn't ruining the playoffs, Jamal Murray ruined the playoffs when he did that stupid boneheaded move. If the item had injured Ant for the rest of the playoffs then everyone would agree he should be suspended.
