HOW THE 2013 "24 UNDER 24" RANKING WAS DETERMINED
Players who are 23 years old and younger as of the final day of the 2013 MLS season – in this case, MLS Cup on Dec. 7 – were eligible for inclusion. Votes were collected from the MLSsoccer.com editorial staff and various American soccer media members.
The voting panelists rated players based on the following five criteria:
- Technical (skills, dribbling, shooting, first touch, heading, etc.)
- Tactical (positioning, reading game, soccer IQ, etc.)
- Physical Attributes (speed, endurance, strength, vertical leap, etc.)
- Personality (marketability, media savvy, quotability, charisma, intangibles, etc.)
- Potential (upside, national team potential, potential future transfer value, etc.)
