Why does the author say this? Even if it's true, medical and training staff quality has a very limited effect on injuries as we witnessed firsthand last year. Some players get hurt a lot. Others, not so much. I don't think too many players at the starting level slack on prevention or conditioning so some of it has to be luck and just how different people are built differently. Was Brett Farvre in better condition than Jimmy Garrapalo? I don't think so, yet the results are vastly different. And Farvre played in a time with less QB protections.
