I think that's a fair assessment to make.
Punk in many ways was even less protected than Bryan was, maybe because Bryan backstage was a more likeable personality - that is a possibility. Both guys you could say were legitimately held back from being the stars they possibly could have been, and Punk preceded Bryan in that fact. I think both men would agree with that. I think it is also telling that Punk - even in his embittered current POV of wrestling - seemed to express the utmost joy that Bryan got his Wrestemania moment, even if it possibly came to an extent at the expense of Punk himself.
