Well he has enough pride to not stoop low enough to whine and demand a rematch knowing all the context surrounding this situation, he may act like that on the outside but he still has personal values he holds such as how he called out mc for looking down on the wrestler dad saying he would ”never understand the true value” of him without fighting him himself
'Is this something to be proud of?' Yes, because you won within the rules you both agreed to, trying to claim it wasn't a real win afterward would be pathetic for your opponent. You're an MMA fighter, you win by MMA standards.
