The Indianapolis Colts (6-5) had to turn around on a short week for a road game against the Houston Texans (7-4) on Thursday night and came away with a disappointing 20-17 loss.

The loss knocked the Colts down a peg in the AFC South standings. Indy went from holding the tiebreaker and the top spot in the division to holding the second spot. Regardless of what happens with the Titans game, the Colts will hold the second spot entering Week 13.

Here are four things we learned about the Colts in Week 12:

Passing offense is being left for dead

There truly isn’t one specific play or group that has led to the fall of the Colts’ passing offense over the last month. It falls on Jacoby Brissett not taking chances. It falls on the wide receiver room being unable to create separation. It falls on Frank Reich for sticking with the run too much at times.

Against a suspect secondary in the Texans, the Colts couldn’t get anything going. Whether it was Brissett failing to force a ball into a tight window or the amount of first and second down runs the Colts ran, the passing offense had no rhythm.

Whatever the case may be, the Colts must figure out how to get the passing game going down the stretch.
