Here’s what stood out from the Indianapolis Colts’ 30-27 win over the Tennessee Titans Thursday night at LP Field: AFC South stranglehold The victory means the Colts have swept all three AFC South opponents on the road to improve to 7-3, three games ahead of the second-place Titans at 4-6. Nothing short of a late-season collapse will prevent the Colts from claiming the division and an automatic playoff berth. Tennessee, Houston and Jacksonville still have to come to Lucas Oil Stadium. Quick turnaround Just when it seemed as if the Colts were going to implode, they drove to a field goal at the end of the first half, scored a touchdown on a Donald Brown run in their opening second-half possession, recovered a fumble on the ensuing kickoff then Andrew Luck ran 11 yards for a go-ahead touchdown. Titans fans blinked in disbelief at a 20-17 deficit. The Colts had scored 17 points without the Titans offense getting a single snap. Another slow start The Colts just can’t seem to make plays in the beginning. About the only thing that went their way in the opening half was the coin toss. They deferred, then the Titans drove 80 yards for an opening touchdown. In the last three games, the Colts have been outscored 66-9 in the first half. This time, they were probably lucky to be down just 17-6, considering how easily the Titans moved the ball. Colts lose composure Chuck Pagano’s team entered as the NFL’s least-penalized team with just 33 penalties for 262 yards. But the Colts defense lost its composure in the second quarter with three personal fouls in one drive that helped the Titans add three points. The first call was questionable as replay showed pass rusher Robert Mathis letting up as he hit Titans quarterback Ryan Fitzpatrick, but referee Mike Carey saw it otherwise. Colts cornerback Cassius Vaughn got into a tussle with Titans wide receiver Nate Washington and was flagged. The worst and most obvious call was Colts outside linebacker Erik Walden, who ripped the helmet off tight end Delanie Walker’s head. Walden, who also head-butted Walker, can expect to hear from the league office.
