Yah, more and more we're seeing how non-UFC accolades come at a severely reduced value. Jake hasn't proven a thing in UFC; you might as well say X player is great because he won championships in the minor leagues (but not quite).
I get that he had a nice run and putting Henderson on your list is great notch. I don't like to tarnish figher's wins but that one does seem a little less impressive considering context.
Maia has had a line of solid wins in the big show and looked fairly dominant doing it.
