Question: who was the mp in the dirty dozen

title: The Dirty Dozen
text: Jim Brown , the Cleveland Browns running back , announced his retirement from American football at age 29 during the making of the film . The owner of the Browns , Art Modell , demanded Brown choose between football and acting . With Brown 's considerable accomplishments in the sport ( he was already the NFL 's all - time leading rusher , was well ahead statistically of the second - leading rusher , and his team had won the 1964 NFL Championship ) , he chose acting . Despite his retirement from football more than 50 years ago , Brown remains the league 's 10th all - time leading rusher , the Cleveland Browns ' all - time leading rusher , and the only player in league history to have a career average 100 yards per game . In some form of tribute , Art Modell himself said in Spike Lee 's Jim Brown : All American documentary , that he made a huge mistake in forcing Jim Brown to choose between football and Hollywood , and if he had it to do over again , he would never have made such a demand . Modell fined Jim Brown the equivalent of over $100 per day , a fine which Brown said that `` today would n't even buy the doughnuts for a team '' .
