When you want talk directly to people, and avoid all of your emails being deleted, you go to the people in decision making positions.
The Pre Draft Combine brings scouts from around the world to one location for you to speak with directly.
When your emails go unanswered, and you are not getting the opportunity you think you should be getting, doesn’t it make sense to ask those people directly why?
Stop wondering, and start taking control of your career. Develop your network, and see a change.
