I understand letting people back into the finals after falls, but they must draw the line at some point. You see way more trips, collisions, and falls among elite athletes compared to high school or even college. This is because I find them to be too stubborn to accept the fact that they must move over, go around, etc. Why employ tactics and move to a different lane when you can stand your ground, fall, and move onto any final you want. Heck, you can be impeded slightly and get granted a chance to compete for an Olympic spot (engels in 800). Part of racing is dealing with falls and people around you. I get that its out of your control sometimes, but I feel like there shouldn't be people getting into finals with such ease. Falls are part of racing.
