KROGAN RULES FOOTBALL
meters (this is the FUTURE!). 4 downs to go 10 meters.
No roughing penalties.
No personal fouls - except for crest-grabbing.*
You are allowed to throw one punch per play.
No holding penalties.
Encroachment/false start penalties remain.
No restrictions on who can receive.
No late hits, but the punch limit stands. (that is, a late hit would count as a punch)
Uniforms are not padded. Krogan are born
with armor. No helmets.
No celebration or taunting penalties. Starting a fight on the sidelines gets you thrown out - a full team-on-team fracas results in a loss for both.
Killing an opponent intentionally
gets you banned from the sport. There is a review committee especially for this, and they average five cases per year. Most are ruled unintentional.
No use of biotics.
No holding penalties. This is where the one-punch rule comes in the most useful, to get the defender off you!
* This rule would have been added to the sport years after its creation, at the pleading of team managers who were losing too many of their players to broken necks. This, and other rules reinstated to the krogan version of football for safety (because remember, American football has the pads/rules in the first place because of serious injuries and deaths to players in the past), are extremely
unpopular with the krogan crowd. A referee generally only enforces the rules when the infractions are blatant, and the entire krogan population of the stadium will enthusiastically boo the call.
