It is up to the league to bring in ownership groups and managements that will bring the highest level of play. The 7 on 7 system is not an issue, just like the NIFL's 8-man system wasn't an issue when Black Hills popped Southern Oregon 108-3 (and SO wasn't missing that many of their players). The 8-man system wasn't an issue last year when Sioux Falls popped Peoria 70-0 in the UIF.
Outdoor football has blowouts just like the indoor game. It's just that in the indoor game, since teams score so much more often, the blowouts can get much uglier on paper than perhaps they otherwise would.
Teams need to do a better job of bringing in better players. The WIFL plays with virtually the same exact system as the AIFA. Why haven't they had 80-20 games or 78-6 games like the AIFA did? Ah yes, disparate talent within the league.
When the UIF has a blowout somewhere (and it's indoor football, that will happen even when teams are closely talented as in the UIF), I will make sure to complain they need to change the game system that has been used since the 1998 PIFL, because it obviously doesn't work. Or...maybe there's something to the whole "as leagues and teams mature, the long-lasting teams all figure out what talent is needed to win and stay competitive" theory.
Though yes, mistakes have been made, the CIFL is still only in its second year of what is a BRAND NEW game system to indoor football. Of course it's going to take teams all over time to figure it out (NY/NJ nonwithstanding, they'd be killed in any league that's still playing).
