Slate has an article about when teams in the NFL should go for a two point convert. From the article, "NFL teams have a 47.9 percent success rate on two-point conversions." What's the CFL success rate when going for two? Higher or lower than the NFL? I'm inclined to say higher, although I don't have a lot of evidence. Maybe the passing completion percentage is higher in the CFL. Certainly the end zones are way larger so that has to help.
What if it turns out that the percentage is higher than 50%? Should teams always go for two? What if your team has a good offense and the other team has a bad defence? Should that affect the choice? I doubt CFL coaches would always go for two, but something to think about.
