However, just a couple of losses derailed the fighter's reputation due to the high expectations levied on him. Northcutt spoke to MMA Fighting about Raul Rosas Jr.'s first loss to Christian Rodriguez at UFC 287 and said:“I actually saw his fight. He was going at it. I saw a couple of rounds and he was wrestling, wrestling, wrestling. I think he’s got a lot of talent. He’s 18. He’s got so much time to keep growing and learning and improving. Being young like that, you have a loss — try to take it as a learning experience.” [h/t MMA Fighting]'El Nino Problema' will look to bounce back strongly from his first loss and regain the momentum that saw him get signed by the world's premier mixed martial arts promotion.
