what is a cb in football

In football, CB stands for cornerback, which is a defensive position in the game. The cornerback guards against the offensive team, particularly any player that may catch the football on the offense, such as the wide receivers (WR), tight ends (TE), or running backs (RB). Most of the time, cornerbacks line up opposite the offense’s wide receivers, guarding them in order to prevent a completed pass. The cornerback’s chief responsibility is to defend against the offenses pass. They can also blitz and defend against offensive running plays. The cornerbacks responsibilities vary depending on how the defense assigns protection to its defensive secondary.
