“Look. I ain’t no sore loser. I take my wins, I can take my losses. I’m a true champion. I came out here. I did what I had to do, and I went out there and I did my best. I don’t care what anybody says man. I am as real as they come. This is ‘the takeover’ man. We don’t stop. We keep coming. Yo. I love you all. I won this fight.
“You know what man? I know what it is. I know how these people work. The referee knew I won tonight. Everybody knew I won tonight and I’m just thankful…I don’t believe it was a close fight at all. At the end, I scored it 10-2!”
