Darren Rovell has challenged Dana White to a debate after the UFC president referred to him as a “dips**t” for questioning Amanda Nunes’ marketability.The feud between Dana White and sports business analyst Darren Rovell regarding Amanda Nunes’ marketability can be traced to a few years back. Then-UFC women’s bantamweight champion Amanda Nunes had just won the UFC women’s featherweight title by dethroning Cris Cyborg via first round KO at UFC 232 in December 2018.Darren Rovell subsequently tweeted and wrote blog posts wherein he emphasized that by beating Ronda Rousey in 2016 and Cris Cyborg in 2018, Amanda Nunes had singlehandedly killed the two biggest draws in women’s MMA. He highlighted that this was “brutally damaging to UFC”.Rovell opined that Nunes had nowhere near the drawing power of Rousey, Cyborg, or even fighters like Miesha Tate, Joanna Jedrzejczyk, and Paige VanZant. He also noted that Nunes herself had admitted in a past interview that she wasn't the kind of women's MMA fighter that the UFC usually promotes.Darren Rovell@darrenrovellBetween Rousey and Cyborg, Amanda Nunes has singlehandedly killed the most valuable women in the sport.Brutally damaging to UFC.Nunes isn't in the same marketing ballpark as either of those two.10:27 AM · Dec 30, 20183133554Between Rousey and Cyborg, Amanda Nunes has singlehandedly killed the most valuable women in the sport.Brutally damaging to UFC.Nunes isn't in the same marketing ballpark as either of those two.As seen in the video below, Dana White hit back at Darren Rovell at the UFC 232 post-fight press conference back in December 2018 for questioning Amanda Nunes’ marketability.CJ Fogler@cjzer0Dana White does not like Darren Rovell much12:03 PM · Dec 30, 201887421362Dana White does not like Darren Rovell much https://t.co/ZUNMmx82u5After Amanda Nunes’ second-round submission loss against Julianna Pena at UFC 269, Dana White took another jibe at Darren Rovell.
