Get that degree. It used to be that major networks wanted a good personality on the screen, but this profession now demands a degree. Unless you played professionally, most sports shows won't look at you if you haven't graduated form college.
Look for internships that matter because the degree will only get you so far. Most cable companies and networks want someone who is willing to work hard. They want someone who has worked in the booth during a game and sees what happens.
Focus on broadcasting. A lot of people will take a job in another part of a sports show in the hopes of switching over, but that can lead them down the path of not being on air. ESPN broadcaster Sean McDonough often tells students that they are better off cutting their teeth broadcasting Little League games than working behind the scenes of a college or pro game.
Send out resumes and videos. Once you start getting some games--even if it is Little League--start spreading the word to companies and networks that may need you. Think outside the box on this one. There is more than just NBC, ABC, CBS, ESPN and Fox Sports now. Look at Web companies.
Remember to keep practicing. That means hone your craft. Examine your mistakes and your success. Get guidance from people already in the business.
