Will it challenge the CFL if there is a link to the NFL as players decide to play closer to home to be under the eye of the NFL? Contracts and money will be an issue putting the CFL still in a good position.
It is trying to be a Spring League and that is a challenge in the USA as other sports come into the picture too.
