I obviously can’t prove my theory. But it is this. I believe that floor is not uniformly level from one end to the next. So players jum a certain way, always expecting to land a certain way. But the smallest of errors in their perceived distance (from top to bottom) causes them to land with more or less force. Multiply this effect over time and add in perhaps some preexisting physical conditions, and you could have a toxic brew. Someone needs to do a complete surface analysis of the Trailblazers floor. Or i believe this will continue to occur there.
