He's smart enough to figure out what went wrong:
"but just me being too over-cautious is what did me in. I didn't let my hands go, obviously, everyone knows I didn't throw very many punches and when I did I was hurting him and just didn't capitalize on it, man. I didn't keep going and that's my own fault. My own rustiness, my own lack of a killer instinct when I was in there just from being out of the ring too long."
And I'm sure he'll fix it in the future!
