"Everything you know is wrong! Black is white, up is down, and short is long...."
Both teams have been the opposite of words that described them in late August.
Weren't the Titans considered an uncertain entity and the Steelers marked by many as a Super Bowl favorite?
Heading into Sunday's key affair at Heinz Field, it is the Titans who boast a league-leading defensive unit, and the Steelers lost in an identity crisis.
Consider that the Steelers overcame a slew of injuries to win the Lamar Hunt Trophy and represent the AFC in Super Bowl XLV only months ago.
Conversely, the Titans ended 2010 in meltdown fashion. The antics of quarterback Vince Young and rapid descent in the standing by Tennessee (who began the season 5-2) were catalysts for change. Jeff Fisher was removed from his rank as the NFL's most tenured head coach, and the offseason brought new faces.
Mike Munchak became the new coach, Matt Hasselbeck joined at quarterback weeks before the start of the regular season, and expectations were quite pedestrian for a squad that finished 6-10 last year.
So, common sense would indicate a clear win for the 'Burgh, right?
The young NFL season has seen many surprises. The Titans are among the unexpected success stories, heading to Heinz Field with a 3-1 record.
Meanwhile, Pittsburgh has been unable to run the ball or stop the run, trademarks of the practically patented "Steelers way." These struggles are coming from a squad that returned nearly all of its starters on offense and defense to defend their AFC Championship.
In a way, the Steelers struggles so far in 2011 can be summarized by another lyric from the aforementioned song:
"...and everything that you have done which is so important doesn't matter! Everything you know is wrong."
In other words, the performances of these squads prove that last season is history, and the accomplishments of 2010 do not matter with respect to now.
Currently, the Titans look to extend their surprise winning streak to four games, while the Steelers look to reclaim the swagger and pride of a champion and avoid a losing record.
Will Tennessee bring their three wins and beat the city of Three Rivers? Or, are the Men of Steel primed to send them back to Nashville with a Titan-ic letdown?
Here are 10 things for Steelers fans to observe during this Sunday's pivotal AFC contest.
