When I first watched this fight I saw a what appeared to be a straight right by Thornton that landed flush and down goes Erskine - enter doubt, angles, etc..
I will go with my gut...Erskine went down in a heap
"Courage is not the absence of fear, but rather the decision that something else is more important than fear. The brave may not live forever, but the cautious do not live at all." Fear always springs from ignorance."
-Ralph Waldo Emerson
