It seems like there is going to be a shitstorm of controversy whenever the year ends in 4(84, 94, 04).
1984 - BYU goes undefeated on an extremely soft schedule, beats an unranked Michigan team in the Holiday Bowl, and wins the national title. Had it not been for a unsportsmanlike penalty on the Sooner Schooner wagon at the Orange Bowl, Oklahoma would've beaten Washington and probably would've won the national title. Sporting News would vote Florida #1 in their own poll.
1994 - Nebraska and Penn State both go undefeated. However Penn State gets screwed due to Paterno pulling the starters at halftime and allowing garbage points. Also Penn State gets screwed due to their bowl matchup, having to go to Pasadena to play Oregon while Nebraska got to play Miami at the Orange Bowl.
