Soccer (futbol) refereeing is far more sketchy than football. In addition to the normal complaints about incompetence that all sports fans have about referees, you have the added corruption. People bitch about the refereeing the in Super Bowl, and justifiably so, but no one seriously thinks the refs are trying to give the game to a particular team (at least no one rational). Moreover, you have fans so rabid (and devoid of sense) that they make Raider Fan look like your average girl scout.
The Bears haven't had even a decent QB since they screwed Flutie over in 1986. Before that, McMahon was the only quality QB since Bobby Douglas, and McMahon was injured 50% of the time (thank god for Steve Fuller in the 1985 Super Bowl season).
