In Million Dollar Baby, there is a scene where Eddie "Scrap Iron" Dupris(Morgan Freeman) decides to teach a lesson to some young boxers at the gym who are picking on a weaker, less-experienced boxer. Eddie is old, blind in one eye, appears to have not boxed nor trained for years, and only puts on one glove. Is it realistic that he could have knocked out the young, fit, up-and-coming boxer punk within just a few seconds, with just 3 punches? Did it help that he hit the kid with his ungloved fist?
The match starts at 2:20 in this clip.
