Jeff Berryhill oversees one of the most complex sales operations for any professional sports league. Located in Blaine, Minnesota, the National Sales Center helps develop "fresh out of college" graduates and transforms them into cutting edge sports sales executives for Major League Soccer. Berryhill discusses some of the things that the NSC candidates go through, including dorm life, with no guarantee of a job at the end of the training cycle. Berryhill talks about what makes a great sales staff go, how he has helped place great young executives with MLS franchises, and why it is important to be mobile in the sports industry if executives want to stay in the sports industry.
