A piece of protective equipment used in football and is attached to the bottom of the shoulder pads. Although it is geared towards protecting the player it is mainly used to increase swag points while on the football field. Don't get a back plate unless you have major swag and are a key player on your team.
Look at number 88, he has a back plate and won't even see the field. Thats a disgrace to the game
