Live Chat: UFC 221 Preview, UFC 222 Main Event Mess, Corner/Referee Stoppages

At UFC 221 this weekend, Luke Rockhold and Yoel Romero will battle for the interim middleweight title. We'll preview the event plus look at the fight card. UFC 222 still has no main event. It could be Frankie Edgar vs. Brian Ortega and the event turned into a Fight Night, but nothing is official. We'll game out what could happen. Plus, we're still in the shadow of Mario Yamasaki's non-stoppage at UFC Belem. What lessons can we draw about why fights aren't stopped sooner? This is the Promotional Malpractice Live Chat.
