Wise words from the Prophet Muhammad that’s often loss in the “win now” world of sports. FC Dallas has historically done this well when it’s come to their players and their development, but at some point in the reality of professional sports, players have to deliver something of value to the team or risk being cut.
What that value is entirely subjective, but there are markers that can be used to determine what that is. For example, defenders should defend... scoring goals is bonus, but their primary value is helping keep the team earn clean sheets.
