This week it was a flag fest. I have to assume that the NFL didn't like being criticized with the comparison and put the word out: call it like we do or else. It was fun while it lasted (all of one week)
It's essentially the equivalent of AAA in baseball. There was a lot of talent out there, but an awful lot of dropped balls, poorly run routes, and failure to click inside the 20. Maybe they'll get better as they play more together, but there were just too many field goals for the general public.
Will it survive? Probably for a couple seasons, especially if some of the AAF end up in the NFL next fall. If not, it will fall into the category of USeless as the USFL, as Wobbly as the WFL and as Xcruciatingly bad as the XFL, and be a trivia question by 2021.
