For both the Xbox 360 & PS3 after tonight, the league ranking will be compressed. Basically, all teams will keep their same rankings, but higher rank teams will have their ranking points compressed to bring it closer to the middle of the pack teams (div 2 and below). Thus allowing teams in div 2 and 3 to make a chase for div one and earn a playoff spot where more information will occur in the next weeks.
