Football is now a pass-happy game. It makes much more sense to have three downs, not four. Its games move faster. Forward motion before the snap, something I would've opposed, actually opens up the game and makes it more exciting. Live ball in the end zones. No fair catches. Deeper end zone. Wider field.
The Argonauts are still around but even after somehow winning the Grey Cup a couple years ago, they sunk back to the bottom and draw few fans. The league will actually expand in a couple years to Halifax. My suggestion has been that they expand to select American cities in the North, where they would be the only pro teams in town, and where they can sign hometown college players, like: Boise, Madison, Fargo/Moorhead, Omaha, Syracuse, Tacoma or Spokane. When they tried this in the 90s, they expanded in the South, and other than Brimingham, there wasn't much support.
