$(1)$ With the disturbing news that nearly all of the brains of deceased football players tested for chronic traumatic encephalopathy $($CTE$)$ indeed had this terrible brain disease, the National Football League and the Canadian Football League are taking steps to curb head hits on the field. $(2)$ The new Canadian rules differ from the NFL$\text{'}$s in three ways. $(3)$ The first difference is in their practice methods. $(4)$ The CFL has barred players from full contact practices, meaning that players cannot ram into each other. $(5)$ While Canadian players must wear helmets during practice, they do not wear protective padding, which makes them less likely to hit each other. $(6)$ Americans, on the other hand, have not been as cautious; instead they have merely limited the number of padded, full$-$contact practices to fourteen during the regular season. $(7)$ The second difference is time off. $(8)$ The CFL recently added a third "bye week," or week off, to its $18-$game season to give players more time to recuperate. $(9)$ The NFL$,$ however, allows only one bye week in its $16-$week season, giving its players less resting time. $(10)$ Finally, while the CFL plans an ongoing evaluation of these new rules and their effects on player's brain health, the NFL says simply that it will consider the data collected by our neighbor to the north.
