It all depends on how you train. WRT CTE/Concussions, I can't speak to that. No one I've trained with has had that issue, maybe that's more of an MMA thing - ie striking. If you go 100% full competition all the time and never want to tap out - then yes I would agree there is significant risk of injury. But that's true with any physical endeavor. If you instead train with the long run in mind, pick and choose your rolling partners, and tap out when you're not in a good situation then you can mitigate those risks quite successfully. Having weight trained, ran track and trained BJJ, I've had far more injuries in weight training + track despite having far more time on the mats than weight training and track by a very large margin. We're taught in my academy - you are accountable for your own safety. Just tap, come back another day. Fully understand and admit not all schools are the same.
