Every coach has moments where they realize someone is hurting the team’s chances to win. There are many reasons to pull a player from the field. The top reason is an injury that slows the player down and therefore risks further injury to himself or others. A close second is a player that lacks confidence. Lack of confidence is like a contagious injury. Doubt can spread and an unconfident hesitation can lead to a situation where a player gets hurt or causes the injury of another.
