I am not upset, because it's just a game, but I will put it to you this way:I get the feeling that you are a little bitter because those late '90's Bronco teams are kind of forgotten about because they fell in between that NFC run of dominance and the Patriots dynasty.
Who did the 97 Broncos beat in the SB, and who did those NFC teams (from 84-96 beat) in the Super Bowl?
Well, the Broncos beat the best defense in the NFL and the three-time MVP in Brett Favre. Their offensive line neutralized a behemoth in Gilbert Brown, and Tony Jones did a great job against Reggie White (and, they did a great job on Leroy Butler as well).
Who did these NFC teams beat in the SB? Usually nobody special. There were only two times in that 13-year span that the AFC team was favored: Super Bowl XXII (Den-Was) and SB XXV (Buf-NYG).
Miami and Denver were one-man bands. And, when the 49ers played the Broncos, John Elway was sick as a dog with a bad cough, and Wade Phillips was running the wrong defensive scheme (a static 3-4 with the safeties wide).
As for the Bills, they should have won the first one, but those teams weren't as great as people think. They got there the last three years (1991-93) because the AFC was so inept. Chris Mortensen said in The Sporting News after the first Dallas loss that the Bills should have traded either Jim Kelly or Thurman Thomas. I would have traded Thermal, and he wouldn't have been the only guy I got rid of.
Then, after the 49ers defeated one of the worst teams to make the SB in the 94 Chargers, the Cowboys may have won the next year because Neil O'Donnell threw the game (it looked like the fix was in on those two INT's).
And, in 96, the Packers beat the third-best team in the AFC.
Overall, that NFC run wasn't as impressive as it seemed at the time.
