Jiri has done Ayahuasca half a dozen times and has actively pursued some pretty advanced spiritual practices. So, I would say he's far more advanced into traditional wisdom than you're giving him credit for.
Comparing him to Ferguson and Diego, here is awful, these are guys who get sucked in by woo woo spiritual nonsense.
That's very different from core traditions that actually do have a lot of power in them.
Magical thinking helps more than hurts, you just aren't as aware of the countless cases that aren't publicised in combat sports or athletes in general.
