A long-term break from extended stress and athleticism, followed by a return to extreme athleticism, which resulted in a single particularly bad year (2021 - 20 deaths)? Notably there are fewer deaths in 2022 (8) than 2019 (10) 2018 (9), and 2017 (10). 2023 looks to be in keeping with that trend. It looks far more like 2021 was a single outlier year with reasonable explanations than an 'uptick', which implies an ongoing trend, which the data you're showing simply doesn't show. Another factor could be that those who had congenital heart conditions who would have died in normal play in 2020 (2) are among those who died in 2021.
