On this week's episode of What the Heck, MMA Fighting's Mike Heck speaks to Marlon Vera (5:25) to recap his first-round TKO win over Sean O'Malley in the UFC 252 co-main event.
In addition, fellow UFC 252 winners Daniel Pineda (33:18) breaks down his TKO win over Herbert Burns, and Vinc Pichel (55:11) talks his unanimous decision win over Jim Miller.
Finally, Derek Brunson (1:14:45) gives his perspective on the top storylines from Saturday night's PPV event in Las Vegas, Jon Jones vacating his light heavyweight title, and explains why a fight with Jack Hermansson makes the most sense after his win over Edmen Shahbazyan.
