Besides sports management, what other majors can I take that will help me be a good sports agent ?
You can read the first 24 pages of a book, "The Business of Sports Agents" here: http://bit.ly/1EsoWGb
Also, you can read what the Houston Chronicle, the biggest newspaper in the Houston area published recently about sports agents: http://work.chron.com/average-sports-agents-commission-21083.html
Jordan, to be honest, I know two people who attempted to become sports agents, one of whom went to a graduate program in Sports Management at Ohio State University - and neither was able to become a sports agent. As I understand it, becoming an attorney is the best way to become a practicing sports agent - because there are so many contracts and negotiations involved in the job. A law degree could serve you well in many ways while you try to break into sports agency and you may find a good job as an attorney outside the sports field entirely. It's good to have a back-up plan when trying to break into a field with very few jobs and many people who want them.
