Lamonica
If the Bills had won the AFL champoinship that year (they lost 31-7), they'd've faced the Packers in SBI. The Bills stacked-up much better against the Packers: KC was the AFL's best offensive team (about 90 more points scored than Buffalo), but Buffalo's defense was head and shoulders above KC's.
Superbowl I: When Jack Kemp gets injured in the first quarter, his backup, Darryl Lamonica, comes in to lead the Bills to victory with his fourth-quarter bomb to Elbert Dubenion.
If that would have happened, Lamonica doesn't get traded to the Faders the next year, and maybe the Willie Brown trade gets butterflied away that year as well. Then, Willie goes into the HOF as a Bronco, if he goes in at all(since the HOF voters are so anti-Denver).
Here are some more:
1. Houston beats Buffalo instead of blowing a 32-point lead in 1993--Houston beats Pittsburgh, but lose to Miami in the title game (and still moves as per OTL). Miami, in turn, loses to Dallas in the Super Bowl, though with Marino it's not a blowout.
I think that Houston would have went all the way if they didn't lose to Buffalo. They could have beat Dallas that year. Then, the Oilers go back the next year, and Dallas beats them this time. However, the Oilers end up staying in Houston, they don't break up the team, and Moon retires as an Oiler.
2. The Dolphins don't have as many turnovers against the Patriots in the 1986 AFC championship game--The Dolphins beat the Patriots (the Dolphins were the only team to beat the Bears in the 1985 season), but lose as Chicago takes its revenge for losing to Miami (IMO, no one could beat Chicago that year in the Super Bowl).
That loss by Miami wasn't an upset. The Fins deficiencies(running game, defense) caught up with them that day.
3. The Pittsburgh Steelers don't release Johnny Unitas before the 1955 season--Like Dan Marino, Unitas was from Pittsburgh, but played for another team. The Steelers probably win a couple of NFL championships and still win the Super Bowls in the 1970s. Baltimore fans aren't as angry about the Colts leaving as they were OTL.
I agree about the Steelers possibly winning championships in the 50's, but they probably don't have the dynasty that they had in the 70's.
4. Denver beats Jacksonville in the AFC divisional playoff in 1996--Denver advances to the AFC title game and beats New England. However, they lose Super Bowl XXXI to the Green Bay Packers (the Packers were the better team, IMO) in one of the better Super Bowl contests. They get their revenge the next year when they beat the Packers.
If Denver would have lost to the Pack in 96, I think it would have been a close loss. Then, Elway and the Broncos come back with resolve, and beat the Pack in SD in 97.
5. Minnesota kicker Gary Anderson doesn't miss a field goal in the NFC title game in 1998--The Vikings win the NFC title game and go on to face Denver. It is a high scoring game (both teams have good offense) and the Vikings finally win their first Super Bowl.
This is a continuation of the previous question. If Minny wins and goes to the SB in 98, the Broncos win because they would have pounded the rock against an average Minnesota D. TD wins his second straight MVP, and, because Elway lost two years previous, he comes back in 99, and the Broncos win again over the Rams. He then retires, and gets inducted into the Hall in 05 with Marino, Steve Young, and Barry Sanders. It is considered the best HOF class of all-time. Meanwhile, it butterflies away TD's 99 injury, he goes on to play until 04 or 05, amasses 12,000 career yards, and is a HOF lock in 09 or 10.
