If you are 17-20 than you are probably a little dumb
The problem with the CHL is once they make the decision which was likely made in their 14-17th years is that a company is making profit and using leverage to deter you from bettering yourself. If they make profit on and control your career trajectory than they are using you. Its not about the CHL taking a bigger chunk but more about them taking it all and having the audacity to ask for control of the players lives while they remain in control or reap the benefits.
