Good day, everyone

 I really don’t like the whole knockout thing in the game, especially when there’s 3 to 4 minute games but there’s nothing  we can do but my question is why doesn’t this apply as well on defense? Why does a defender who stands in the way of a WR as other defenders collide, can still can catch  the ball?  Many times I would throw the ball over the middle of the field, and the linebacker would be coming from the left side and another defender is coming from the right side and they collide into  each other making a rag -doll animation and still somehow manage to have the interception catch 

shouldn’t the knockout apply on both sides of the ball?
