It is hilarious to see so many quickly discount the report of high rates of myocarditis in the B1G and then take a second hand tweet about the NFL as the gospel truth.
That has to deal more with what you want to believe then looking at the facts.
As I stated before, the B1G study was done over a 3 month period by Dr Curt Daniels at Ohio State (not someone who calls himself a Dr on Twitter). It is being publish in a respected scientific journal after it clears peer review.

If you dig deeper into the NFL info, it was not done using a cardiac MRI. It was done using EKG, measuring troponin levels and echocardiograms.
Those that have real scientific training (not those that play like they do on GH) can tell you that the measuring tools are very different. The NFL used tools to check for damage that has occurred to the heart. Damage that could have been caused by acute cases of myocarditis, but not for the presence of myocarditis. The Dr at OSU used a very powerful MRI that allows you to actual look at the heart to see the myocarditis itself (before it can damage the heart).
Again, the B1G was looking for myocarditis, the NFL is looking for damage caused by myocarditis.
Let us ignore the fact that the PSU guy screwed up and said 30-35% when the study actually says 15%. That just distracts from the overall issue, because 15% is still a very high number.
The results from Dr Daniels research show that Covid-19 is linked to myocarditis in the hearts of athletes. The level of inflammation may not be to a point where it can cause damage to the heart, but it is present and has the potential. Since we do not know what levels of inflammation are safe, it was in the B1G's opinion to error on the side of safety and wait on the season.
