Three weeks, three close wins, three straight head coaching blunders by Colts opponents.

John Harbaugh is the most recent coach to present the Colts with a gift with his bad decision down the stretch.

Getting to 10-0 isn’t easy, and a little help along the way never hurt anyone.

On Sunday a timeout/replay challenge mishap by Ravens’ coach John Harbaugh helped clinch a 17-15 win for the Colts.

Harbaugh burned two timeouts in one sequence late in the game. The first timeout – the Ravens’ second – was to stop the clock after Reggie Wayne reached for a first down with 2:19 remaining … no problem there.

But with extra time to view the spot, Harbaugh inexplicably tossed his red flag despite the call clearly being correct. If anything, Wayne’s extension of the ball was a yard beyond the spot.

The challenge was denied and the Ravens’ final timeout was burned.

With the Ravens out of timeouts and trailing 17-15, the Colts ran three run plays and drained the clock to 28 seconds before punting. Baltimore ultimately turned the ball over on the punt return, trying to lateral for extra yards.

Had Harbaugh saved his timeout, the Ravens would’ve had more than a minute remaining when they got the ball back and wouldn’t have resorted to desperate measures. And without the lateral attempt, Baltimore would’ve started at its own 40-yard line – a couple of first downs away from a game-winning field goal try.

The week before, we all know what happened during the Colts 35-34 victory over the Patriots.

Bill Belichick’s decision to go for it on fourth-and-2 blew up in his face. But overlooked was his timeout mismanagement. Much like Harbaugh, Belichick butchered his team’s timeout situation.

Before the infamous fourth-and-2 all even happened, Belichick had blown his team’s final two timeouts on the drive.

This became crucial for two reasons:

1) Without any timeouts the Patriots couldn’t challenge the spot on the fourth-and-2 play … which was undeniably a kind one for the Colts.

2) The Patriots couldn’t stop the clock after Joseph Addai was stuffed on the goal line prior Peyton Manning’s touchdown pass to Wayne. Without a timeout the Patriots were left with 13 seconds to get into position for a game-winning field goal rather than 53 seconds.

Three weeks ago, Texans head coach Gary Kubiak also presented the Colts with a gift. With the Texans driving deep into Colts territory late in the second quarter, Matt Schaub completed a pass to Ryan Moats down to the Colts’ 1-yard line.

Moats fumbled near the sideline and Colts defensive back Jerraud Powers scooped up the ball inbounds, but the referees ruled that Moats was down.

Rather than run a quick play, the Texans let the clock run down to the two-minute warning. With another look, Colts coach Jim Caldwell threw the challenge flag and the result was a Texans’ turnover. The Colts’ took possession at their own 1-yard line – a huge play in a game that ended in a 20-17 Colts victory.

Ultimately, the Colts have earned their 10-0 record. But in this time of giving, a thank-you card to Harbaugh, Belichick, and Kubiak from the Colts would be thoughtful.
