This was always a weird idea, considering that the only people who care about American football are Americans. I guess it was worth a try to see if they could build a euro-fanbase, but it seems to have failed miserably. IMO, they should have first tried to build interest in Canada, Mexico, and Central and South America, where people are in the same time zones. Obviously, those markets are not nearly as lucrative as Europe, but you gotta start somewhere. I would start a minor league with, say, 8 teams in the US/Canada and 8 teams in central/south America.
