It was the kind of performance that suggested the Brazilian wasn’t ready for the top level of MMA.That meant that last night, Vieira’s back was against the wall in his fight with Stoltzfus. But thankfully, he showed some improvements to win the fight with a third-round rear-naked choke.Vieira showed far more patience than he’d done before, and didn’t gas himself out by spamming takedowns against his more defensive opponent. Instead, he backed him up and kept the pressure on without being too explosive.INCREDIBLE 🤯Rodolfo Vieira finished with STYLE 💥#UFCVegas31 pic.twitter.com/XTVv8ncUj8— UFC (@ufc) July 18, 2021And when the time came, naturally Vieira delivered the goods, snaking onto Stoltzfus’s back before strangling him with a beautiful rear-naked choke.Will Vieira ever become a UFC title contender? It’s honestly doubtful as he still has holes in his game to fill, but at the very least, this performance showed he does belong in the world’s biggest MMA promotion.
