Any time you have to face Chicago or Minnesota in the title game on the Japan version, it is impossibly difficult at times just to even get a field goal unless you see the patterns quickly or call a great game. You are basically blitzed every time against these 2 teams in the last game. Singletary is not even attempted to be blocked by your offensive line. Minnesota will always block your field goal attempts and extra points. One of the only teams, if not the only team, that can kick a field goal or an extra point against Minnesota is San Francisco. Here are some links to these matchups.
