Personally, I think the league should go back to the old blocking rules for kick/punt returns. I like to see someone break one open once and a while and go all the way with it. Also, all these illegal blocking calls force teams to start deeper in their territory and thus play on a longer field resulting in less scoring.
With all the things that were wrong with the CFL in 2005, I did not think that the rules were among them (the officials' interpretation of those rules may have been a different story however). Does not make sense to me why they changed it for 2006. Any thoughts?
