Background: Robert Lee "Bobby" Dodd was born in 1908 in Galax, Virginia. He was named after Confederate General Robert E. Lee. Dodd was the youngest of Edwin and Susan Dodd's four children.
Context: Another issue of concern for Dodd was Alabama's and other SEC schools' over-recruitment of players. Universities would recruit more players than available space on their rosters. During the summer the teams in question would cut the players well after signing day. This practice prevented the cut players from being able to play for other colleges during the following football season. Dodd appealed the SEC administration to punish the "tryout camps" of his fellow SEC members but the SEC did not. Finally, Dodd withdrew Georgia Tech from the SEC after 1963 football season. Tech would remain an independent like Notre Dame and Penn State (at the time) during the final three years of Dodd's coaching tenure.  Dodd insisted the only reason he left the SEC was due to the "140 Rule", which allowed colleges to over-recruit. The 140 Rule stated a college program could only have 140 football and basketball players on scholarship at any one time, but the teams were still allowed to sign up to 45 players a year. Therefore, if a school recruited its full allotment of players each year it would exceed the 140 maximum even with normal attrition. Dodd would sign about 30-32 football players a year to meet the guidelines, but the other schools in the SEC were offering 45 scholarships a year, and most were allotting all but a nominal amount to football. Players not good enough to fall under the 140 Rule had their scholarships withdrawn before the end of each year by the other schools. Dodd insisted the recruiting of athletes by this method amounted to nothing more than a tryout for a scholarship. Dodd would not allow any of the football players choosing Tech to be dismissed from Tech, because they were not the best players. Dodd said, "it is not the recruit's fault for not making the squad, it was the coaches' fault for misjudging their talents." If a recruit came to Tech, he would stay on a football scholarship until he graduated.  Dodd wanted the SEC to limit the amount of scholarships to about 32 per year, which would keep the other schools from offering 45 scholarships, picking the best, and withdrawing scholarships from the rest. A vote was to be taken by the presidents of the colleges on the issue, and Dodd made it clear that Tech would leave the SEC unless the rule was changed. Bear had promised Dodd he would get his president to vote for Dodd's position, which would have changed the rule; when the meeting was held on January 24, 1964, the Alabama president voted against Dodd's position and the 140 Rule was upheld when the presidents split 6-6. Tech's president immediately walked to the podium and announced Tech was withdrawing from the SEC.
