Objective vs Game play.

I have inquired a few times in past texts as to why there is no definitive meaning to the word HIT in this game. Hit vs body check. What is the difference? Is not a body check considered a hit. In game stats you have hits. You get an objective calling for body checks. After the game. The objective shows 7. The game stat shows 0. A check is the impediment of an opposing players motion by body contact. A hit. Is considered in that same description. The severity may differ, but the outcome is the same. Body contact.
