In his debut he got KTFO'd by Jeremy Stephens, who at the time was a 2-2 guy who then loss 2 in a row right afterwards. Then he immediately lost again to Tyson Griffin who went 2-4 after beating him and subsequently got cut by the UFC. That could've been it. The UFC could've cut him. His only saving grace was that Griffin was a top guy and RDA's fight with him was close and exciting. In a way though, those losses were a blessing in disguise as RDA was relegated to facing weaker competition where he went 3-0, allowing him to improve his game before getting a step back up in competition and we all know the story from there. Stephens and Griffin however continued facing the top guys and couldn't cut it. From 2010-2016, in 14 fights, RDA has had probably the best strength of schedule.
