at first, I liked Goodell. He is pure controversy.
Next idea: A round football field. (prediction) where teams complete laps instead of drives and a score is determined when the offense player with the ball laps members of the defense--like in roller derby.
Bad ideas in the past: Get rid of the kickoff (remember that one?) OK, so a team is down by 14 with two minutes to go and no timeouts. Game over, because you cannot onside kick.
Spreading the league to Europe and Mexico etc. Free agency would be a nightmare. Who would want to go play in Dublin and have 9-hour flights for divisional games?
The Super Bowl in NYC. Yes, you were thinking about the marketing and not the fan base. Postpone the Super Bowl and see how many death threats you get. Play it in a blizzard, and see how many death threats you get.
Rule changes: No grazing of the QB's helmet with any finger, but after-the-play head butts, slaps, pushes, and punches are encouraged.
