When the bell rang, Brad's towering presence was not a factor since the fighters willing went to the ground quickly. Rob started with a couple of controlling positions on the top but did no work to score hits, go for submissions or improve his position. On his second run at Brad, Rob did not show much skill as he did nothing while struggling for a side mount. Brad was able to heist up and attempt his ground and pound. An opportunity came when Rob had Brad in a guillotine but could not hold on. Rob attributed this deficiency due to his shoulder injury. However, I don't see any excuses possible when Brad very slowly positioned himself for a triangle choke. As the choke was slapped on, there were still ways to defend or relief the pressure since Rob was still on his feet. However, Rob sank backwards to his knees, essentially giving up and quickly tapping out.
Finally, the insight this episode provided me is about perspectives. Matt was visibly dissappointed and felt that Rob took the loss as a way out of his injury situation while Rob felt that he had accomplished something by fighting through his injury.
