There is a big co-relation between injuries and vaccinations. These new covid vaccines are doing many damages that are not being covered. Oil industry ran the governments but over the last 5 years its pharma companies....they overtook oil companies are the biggest lobbyists so you are not not going to hear much negativity in the press about these vaccines until many years later.
The number of major injuries this season in MLB, NHL and NBA are alarming after the leagues decided to vaccinate their players. Over 90% of the injuries are happening to those players who took the vaccine! The mRNA vaccines does a lot of things that affect your brain, muscles, joints and cartlidges that may go unnoticed in regular population but are clearly visible among the subset of populations that heavily use those things.
Also covid protocols such as having to wear masks and restrictions on player work out tune ups etc also affect player staying in top shape.
