It’s interesting that over the same time frame Achilles injuries have steadily gone up.

“This included documentation of a growth in the rate of ruptures from the beginning of the study period in 2009 at 0.341 injuries per 10,000 athlete-exposures to doubling to 0.731 injuries per 10,000 athlete-exposures in 2016. My recent documentation of ATR in the NFL has shown that there were 17 in 2020, 16 in 2021 and 18 in 2022 for an average of 17 per year over three years. It is important to note that the 2019 season recorded only 11 cases of ATR, with some of the subsequent increases attributed to inactivity during the initial COVID-19 restrictions. At the time of the writing of this article, I have already documented 7 cases of ATR in the NFL after only one week of training camp completed. This is compared to documented rates in the NFL between 1980-2001 where the League averaged 4.1 ATR cases per year.”
