What's changing about Canadian football and why?

For decades, Canadian football has coexisted along its American counterpart with a variety of distinctions in field layout, rules, and strategies that make the game very similar to what you see in the United States but different enough to stand out.

Phantom Island is presented by Homefield and produced by Michael Surber.
