Since there seems to be some interweb plagiarism going around today, let me give credit where credit ds due, found this stat while reading Paul Kuharsky's AFC South Blog on BSPN.

Red Zone defense during the past 5 games (the win streak):

They have allowed 17 red zone trips (3.4 per game)

They have given up 6 TDs (35% TD conversion)

They have given up 9 FGs (53% FG conversion)

And they have forced one turnover and one missed FG.

Teams have scored 69 out of a possible 119 points.

Rushing stats:  Teams have rushed 34 times for 72 yards (or 2.1 yards per rush)

Passing stats:  Teams have completed a really high 76% of their 17 passes (13 of 17) but for a really tiny 65 yards (3.8 YPA)

The Colts have 1 sack in the red zone in each of their last 3 games.

To give you the other side of the equation, the Colts offense converts their red zone chances in to touchdowns over 71% of the time.

Here is the link, it will give you more words and a pretty chart, but it doesn't give you things like league average and how their defense compares to other teams, but 35% TD% is pretty darned good.
