Deletion of Marcos Oliveira

Comment: I'm unconvinced that Marcus Oliveira has been the subject of multiple published non-trivial secondary sources which are reliable, intellectually independent, and independent of the subject as stated in the |notability guideline for sports. He did not win the IBJJF world championships and even in sources related to that there doesn't seem to be much about him beyond the results. He has not fought in a top tier MMA orgnization, so it doesn't meet the essay for |MMA notability either. I'm leaning weakly to deletion because I do not believe that the IBJJF world championship is the top tier in submission grappling (that would be the ADCC Submission Wrestling World Championship), but I know relatively little about the IBJJF, so perhaps there could be some basis to keep the article, although I don't think so
