With Ronda Rousey finally making a long-awaited debut appearance for the WWE last year, 2019 will undoubtedly be a year that continues the trend of the lines between pro wrestling and UFC being blurred. It is not just in terms of personnel that this process could be accelerated; the mannerisms seen in fight promos, and the behaviour of main players like McGregor and Nurmagomedov, are also more reminiscent of the WWE’s madly-theatrical overtone. For better or worse, this is now a norm within the UFC franchise, giving the powers that be some solid justification to revive WWE themes as UFC walkout music in 2019.
