I love CFL football but I do agree with some of the points. Pass interference had swung way too far a few years ago. I had no idea what it even was anymore. I would watch NFL games and enjoy them more because they allowed the receivers and DB's to compete more. Since the commissioner stepped in a couple of years ago, it has become far better and the games are more enjoyable. I prefer the one challenge per game rule, but it is working okay this year by allowing a second.
I often wonder if we would be better off to just ditch the challenge system. There are automatic reviews now at the right time anyway. Most instant replay shows that the officials make the right calls almost all the time. Fans are selectively blind or hallucinogenic when it comes to officiating and they see things that aren't there regardless of whether there is a review or not.
Other than that, I think the game is doing very well. They need to tighten up on the head injuries though.
