MVP. Most. Valuable. Player. The award, really, is named wrong. In any sport, when the MVP award is handed out, it is never actually voted upon based on which player has the most value.
In NFL, quarterbacks would win it every single year — they do predominantly win it, but the fact that Aaron Donald and Todd Gurley are being considered this year proves that ‘value’ has little do with it.
In the Premier League, the same award is called the Player of the Year: literally, the best player of that particular year. What MVP tries to do is define ‘best’, using the word ‘value’.
