Task: Question Answering
Input (English): passage: In gridiron football, the utility player is often capable of playing multiple positions, and often they may play both offense and defense. The concept was far more common in the early days of football, when pro teams used their best athletes as many ways as possible, and substitutions were far more restricted, meaning players had to stay on the field for offense, defense and ``special teams''. This was known as the one-platoon system.
 question: can you play 2 positions in the nfl?
Output (English): Yes
