Indianapolis Colts – 2005
Everyone thought that this was Peyton Manning’s year after a glorious season. They went on a 13-game winning streak before easing off the gas ahead of the playoffs. A Super Bowl victory appeared to be inevitable but the Steelers burst the Indy bubble (via 247 Sports).
This Pittsburgh team was much better than their seeding suggested. They narrowly lost out on an AFC North title and had a brutal defense. Manning discovered this the hard way after they sacked him five times. Finally, Mike Vanderjagt missed the all-important kick to seal a Steelers’ win.
