With a pick-six less than a minute into the game, two missed field-goal tries and some painful penalties, the Titans put themselves in a deep hole they couldn’t get out of against the Colts. That’s now two home losses where they’ve been outclassed by better-caliber teams, giving them a clear measuring stick to aim for — one they can’t quite yet reach. The most concerning element was the lack of energy early, and Colts WR Michael Pittman said he could sense it in pre-game warmups. Brian Callahan has a lot of work to do to keep this team competitive. They can build around Cam Ward and a few of their encouraging offensive pieces, but they’ve been borderline anemic offensively for stretches and not much better defensively. With three straight (and four of the next five) on the road, the Titans have to turn the tide quickly or risk another long, losing season.
