It takes just one poorly chosen Jenga piece to pull down the whole tower. While the structure may seem stable and secure, if the wrong one is selected when trying to parse it through a tight gap, it will all come tumbling down around it.
This image is a brilliant analogy for the importance of certain players in certain teams. Take Manchester City without Fernandinho this season. Atlanta United without Miguel Almiron. D.C. United without Wayne Rooney.
These players are the ‘Jenga pieces’ of their respective sides. While everything may look smooth and cohesive on the outside, take just them away and suddenly the whole team crumbles around them.
