Rather drastic idea ...in brief I say the following including those that won't happen like an overtime overhaul ...otherwise I say the CFL game needs far fewer improvements than does the NFL for sure!
Try to read slowly please before commenting too, as I have seen there is so much misunderstanding if you read too quickly with regard to the rule changes.
Note that one rule change I had desired with regard to a penalty of only 5 yards instead of 15 on punts in the event a bouncing ball strikes a player on the kicking team before it is touched by the receiving team is on the table and likely to be approved by the CFL.
Overtime -- No More High School Scrimmage
Sudden death after each team gets one possession with all the rules of the regular game in place instead of the current super lame high school practise scrimmage format. Sure no format will make everyone happy, but that is the simplest solution that ensures continuation of the game instead of introducing a practise scrimmage after an otherwise awesome game with ALL the rules of football intact.
Single/Rouge -- No Reward For Utter Failure & Extreme Kicking Inaccuracy From Short Range
ZERO points for any kick out of the end zone that does not bounce in the end zone first and thus would be deemed to have been returnable.
10-yard Roam Zone For Ineligible Receivers Instead Of Only 1 Yard For Forward Pass The Crosses The Line Of Scrimmage-- Fewer Ineligible Receiver Penalties & More Open Offensive Play
Still no ineligibility of course for ineligible receivers/offencive linemen unless specified otherwise under existing rules for offside passes (see CFL rule book), but these players are allowed to roam up to 10 yards from the LOS to set up blocks instead of the current only one yard. Pass interference would be called all the same under existing rules.
Note that this matter differs from existing rules with regard to screen passes, which are forward passes BEHIND the LOS, for which the offencive linemen can roam all the same as on any running play subject to rules on interference as well.
Safety -- Prohibition Of High Hits Above Shoulders To STANDING Players Outside Of The Tackle Position, As Well As Any Players More Than Ten Yards Beyond The Line Of Scrimmage On ANY Passing Play
Essentially the game remains full-go in the designated area between tackles according to existing rules that apply otherwise as well, but no tackling using the head as the primary or secondary point of impact is allowed for the affected STANDING players in the designated open-field area. Some of these hits area already allowed according to some of the rules, but they ought to be broader and simplified for all vulnerable players. See the separate discussion in "Off-Topic" on concussions in the NHL as well. The penalty is 15 yards and possible suspension or ejection of the player based on the gravity of the offence.
