Sensing a tension between the two men that might be used to make better players, coach George Halas (Ben Gazarra) decided to make Sayers and Piccolo roommates at training camp and on the road -- a decision that quickly became controversial, since Sayers was African-American and Piccolo was white. However, rivalry grew into respect, and when Sayers suffered a serious knee injury, Piccolo became the man who helped guide him through the difficult process of rehabilitation. Sayers not only returned to the team, he become a star player, but in time it became Sayers' turn to help Piccolo when Brian learned that a lingering illness was actually cancer.
