They’re the teams within the team — those cohesive little units bound together by their shared responsibilities within the larger team context.

Whether it’s the offensive linemen firing off time after time into those familiar blocking sleds, or the defensive linemen drilling repeatedly on how to shed blockers, or the defensive backs breaking on ball after ball — these teams in miniature hone their tasks on the practice field until those tasks become second nature.
