NFL or CFL: Which one is Safer?

Hello viewers! My name is Rushil Patel and I am a senior at Rock Canyon High School. Throughout the history of football itself, concussions have been a huge point of controversy. Questions about safety protocols, especially within the NFL have risen. To improve player health, the NFL introduced concussion protocols in 2009. However, there have still been a large amount of concussions. In the CFL, players continue to be injured as well. My goal is to determine whether the CFL or NFL is safer for players based on concussions and health and safety protocols.
