Change it to: easy.

Btw, do you play defensive, normal or offensive?

Bad player morale can affect their tackling as well.

On top of that, some players are generally dirty players... I have one like that, he racked up quite a few cards in one season...

You haven't seen Pricop's post that he made the other day where a team got 7 yellows when playing against him.
