I only agree with your first part, they are clearly not in his level however that's not the point of my comment.
My point is that he is one of those guys that have been able to modify his style in order not only to win but to keep his health, this also have been the case in mma, guys that have been able to change their style cause they know the consequences if they don’t don't, unlike those other 3 brainless just bleed guys that keep fighting and taking crazy amount of damage, ironically Justin himself have said he love that kinds of wars more than anything(even winning iirc) but he have definetely modified his style.
My point, yeah fans pay the bills and we all love to be liked but there is no justification to put your health in risk when there are other options.
