I've been using NZA's Madden Editor (I believe there's an '07 version, here's a good repository). I did used to play one team of Herculean demigods against a team (say, the Raiders) with their stats flattened out so well it was a miracle they could walk upright, and that was almost too easy for catharsis. Now, playing Superstar mode where your player is the only real athlete in a league of tranquilized insomniacs -- that's pure joy.
