Donte Moncrief's two-yard touchdown catch from Andrew LuckThe scene: Down 24-0 with 9:34 to play in the third quarter, the Colts took over at their own 35-yard line.The anatomy of the drive: 18 plays for 65 yards, in 8:40Key play: Self-inflicted wounds severely hampered the Colts offense throughout the first two quarters on Sunday. The Colts were still scoreless when they had their first drive to start off the second half. On this 18-play drive, the Colts extended things behind three separate third-down conversions to a trio of different receivers. Andre Johnson, Donte Moncrief and T.Y. Hilton all had third-down grabs to keep things moving. It's this type of variety from the Colts pass catchers that the offense has to continue to rely on.The score: The 18-play drive chewed up nearly nine minutes before the points finally came. Facing a fourth-and-goal from the two-yard line, the Colts put their two biggest wide receivers together to the right of the formation. With Moncrief on the outside running a route towards the middle of the field, and Andre Johnson in the slot heading outside, the Colts ran their version of a rub route. Buffalo defensive backs Bacarri Rambo and Aaron Williams clearly had miscommunication, allowing for Moncrief to make an easy touchdown snag.**
Dwayne Allen's six-yard touchdown catch from Andrew LuckThe scene:Down 27-8 with 8:14 to play in the fourth quarter, the Colts took over at their own 20-yard lineThe anatomy of the drive:9 plays for 80 yards, in 2:18.Key play:With T.Y. Hilton in the locker room, the opportunity was there for rookie Phillip Dorsett to see his first NFL action on offense. On this drive, Dorsett had back-to-back catches for 16 and 29 yards, respectively. This production from Dorsett obviously sparked the Allen touchdown, but it's also going to be needed in the coming weeks. With T.Y. Hilton likely to miss some time, Dorsett should slide into the No. 3 wide receiver role.The score: **Here, the Colts faced a third-and-goal from the six-yard line. This was a beautiful play design and execution. The formation on this play had Andre Johnson to the right, an in-motion Griff Wahlen joining him there and then Dwayne Allen was the in-line tight end, also on the right side. Donte Moncrief lined up to the left but his drag route took him to that right side. After a subtle play fake from Andrew Luck, Allen moved off from his fake pin-down block (on defensive end Mario Williams) and into a pass pattern towards the left side of the field. The Bills were fooled and, when defensive back Aaron Williams couldn't recover from an early slip, Allen was left wide open for his 13th career touchdown reception.
