I see YOU do not understand what an excuse is. An excuse is a reason to be forgiven/excused from a loss, in this case. Saying that you didn't fight well enough and that your opponent was better than you, and then when being asked about how he feels about the fight and saying things which might have helped him, are not excuses.
He did not say "I lost to jones, but that was only because I didn't have cain"
He said that jones fought better than him, and he's disappointed in his own performance.He MAY have performed better if Cain helped him, but he wasn't excusing his loss because he didn't have Cain with him.
You're being an ass.
