Look at all the great HW champions in Boxing from the past ,Johnson Ali Fraizer Foreman Norton Tyson.... I think Brock better watch out because all these Big black guys that go in to the NFL might chose MMA in the future......Even thou theres not a good black HW in MMA now im predicting they will dominate in the future like they do most sports...Whites seem to have the brains but blacks have the brawn....MMA is not mainstream but when it is they will dominate just like Boxing ......Sorry if this comes across as racist in anyway.
