Or you will see more of this happen.
I think players know instinctively when hurdles aren't safe and avoid them. You probably see more injuries when a player goes up high for a pass and someone tackles them in mid air or when they land. That's how Adam Thielan got hurt. It's football. I mean what are they going to kill hurdling over the goal line on 4th and inches? Walter Paytons legacy would be gone in modern days. Dude used to literally jump over the entire pile.
