Given the conversation between Cam and the Principal and the lack of knowledge of the players, it appears to be the first day of Football practice for the Freshman Team. It is incredibly unlikely that the Freshman Football Team would be in full pads on the first day of practice. The amount of time it would take to issue all of the equipment to all of the players would probably take up the first practice. Furthermore, the players should undergo a five day conditioning period before putting on full pads.
