Some say cardio is king in MMA, and that’s why some fans are siding with Alexander Volkanovski to beat Diego Lopes in their upcoming UFC title fight. Volkanovski (26-4 MMA, 13-3 UFC) and Lopes (26-6 MMA, 5-1 UFC) meet next month in the main event of UFC 314 . in Miami, Fla. They’ll be competing for the vacant UFC featherweight title, which was left behind by Ilia Topuria moving up to lightweight. Lopes, who’s on a five-fight winning streak since losing his UFC debut, has quickly become a star in the division. But though respected by many, some remain skeptical of his chances of winning the title – especially after watching him lose steam in his decision win over Dan Ige at UFC 303 last summer
