True but this is tua's 4th,5th?. He isn't a cat. He doesn't have 9
4th and actually he could have 9. Troy Aikman had 10 and still broadcast 25 years after retirement.
There is not definite number of allowed concussions, hell we don’t even have test that determine concussions other than going off symptoms.
There’s zero evidence to suggest a few big hits and concussions is dangerous. It’s obviously not great as opposed to none but all signs indicate taking constant hits in the hundreds and thousands is what causes long term issues and CTE, not a few bad ones.
Everyone is different, it’s the recovery that matters. For all we know Tua is susceptible to concussions easier than most but could recover faster then others while in the other hand a player could be harder to sustain a concussion but recover slower.
Cethan Carter is a good example. Week 1 2022 got a concussion, nobody knew, he wasn’t knocked out cold. He spent the entire year on IR with that concussion, the first of his career. He hasn’t played since. Was always a roster fringe player but still not even a practice squad, could still be from concussion issues. He obviously didn’t recover from that one atleast in 2022 meanwhile Tua was able to get 3 concussions that year and be cleared from 2 probably could of been cleared from the 3rd but I believe Miami was cautious about playing him due to optics. This is because we don’t know how to handle concussions other than check for symptoms. No symptoms then they get cleared.
