Week 3 of the 2012 NFL regular season certainly started off with a bang, with several overtime games and scintillating matchups that went down to the wire. Many teams gave themselves a big morale boost by executing in the clutch.
We saw the unthinkable happen many times, and we were taken by surprise as teams with quarterbacks who aren't always known for clutch executions simply marched down the field to notch big wins.
Let's take a look at the NFL teams that came up big down the stretch to pull out a win.
While Week 3's matchup between the Jacksonville Jaguars and Indianapolis Colts may not have had playoff implications, it was still a huge game with each team trying to get out of the AFC South cellar.
With the Colts leaning on No. 1 draft pick Andrew Luck to take them to glory, many expected Indianapolis to slowly pull away from Jacksonville. But the Jaguars aren't ready to take a back seat in the division, and they showed that Sunday in recording a 22-17 victory.
The Jacksonville offense got off to a slow start, putting up only three points in the first half. But running back Maurice Jones-Drew showed that he's back and as good as ever after his month-long holdout, breaking off a blistering 59-yard TD run. Jones-Drew finished with 177 rushing yards.
But the real gut-check came late in the game after Luck led the Colts to a field goal with less than a minute remaining to put Indy up 17-16. Second-year quarterback Blaine Gabbert then made the game-winning play, connecting with Cecil Shorts on an 80-yard TD pass to seal the win.
The Jaguars still may not have many believers, but they took a huge stride and surpassed the Colts for AFC South bragging rights.
Much will be said of Tennessee's epic collapse that allowed the Detroit Lions to overcome a 20-9 halftime deficit and score the final 14 points of regulation to send the game to overtime.
But the Titans did prevail, 44-41, and second-year QB Jake Locker showed some major guts in the process, completing 29-of-42 passes for 378 yards and two touchdowns, including a 71-yarder to Nate Washington.
The Titans obviously showed that they have their fair share of problems, including an atrocious running game and the inability to stop short first-down passes on defense. But they're far from incapable of winning games against teams of Detroit's caliber.
They proved that Sunday. Perhaps it's much too early to write off Tennessee's playoff chances.
What no one saw coming was 21 unanswered points by the Chiefs and an improbable 27-24 win that left the Saints still winless.
As New Orleans slowly shut down on offense, cornerback Eric Berry swarmed and showed the potential that made him a highly touted draft pick. All of the sudden, Kansas City's defense flipped a switch and went from a unit that couldn't stop the bleeding to an unstoppable force that Brees couldn't pick apart.
A 91-yard touchdown scamper by Jamaal Charles helped fire up the Chiefs, and despite that being their only touchdown, they still won on the strength of six field goals by Ryan Succop and a safety from their swarming defense.
While the Chiefs may not have gotten their season off to a solid start, they notched a much-needed win over a Saints team that just can't catch a break.
