The trend of increasing offence in the NFL and decreasing offence in the CFL has been evident (and increasing in magnitude) for several seasons. In the 1980s and most of the 1990s there was no question the CFL was higher-scoring, with passing a much more important part of the game. That is no longer the case and has not been for the better part of a decade, at least. The NFL is now full of high-powered, pass-oriented offences, and some NFL teams manage to run more offensive plays per game than CFL teams do, despite the fact that they have a 40-second clock and ours is a 20-second clock. IMO the CFL could regain its offensive dominance if it would fix the current clock rules -- i.e. go back to what we used to have -- but there is no way that will happen because the games would be four hours long. The difference is all the commercial breaks -- there are way more than there were 30 years ago, and unfortunately that is never going to change.
