Müller recently made headlines after joining the Vancouver Whitecaps through an atypical but significant mechanism in MLS's single-entity structure called the Discovery List. With that in mind, why is the Discovery List a mechanism in MLS, and should it change or go away? Thomas Müller has officially joined the Vancouver Whitecaps after long negotiations regarding Discovery Rights with FC Cincinnati. "It's like, wait, so we can't talk because [MLS club], who has never talked to me, put [me] on a Discovery List? The agent should be contacted ... MLS should contact either the player or the agent to say you've been added to an MLS Discovery List by a certain team."
