I haven't been boxing in years but I feel like I pack a decent punch, chin? Really untested. I've had many street fights in my youth and sparred a lot and never been hurt but never taken one right on the chin. Infact If I hit myself (lightly) on my chin I can feel the effect
So are you Mike Tyson with a bit of Amir Khan? Or Malignaggi with Margarito on the side? Or Tyson with Margarito's chin?
