Keenum was the game's star for two quarters, hooking up with Andre Johnson on three scores. But Houston sputtered in the second half, giving Luck the type of opening he's taken advantage of often during his short career.
The Colts scored on their first four possessions of the second half, working mostly out of the shotgun and running the ball just once. T.Y. Hilton did his best Reggie Wayne impression with touchdown receptions of 10, 58, and 9 yards in successive possessions. Luck turned it on after a first half in which he faced constant pressure and went 3-of-12 passing for 56 yards.
They have Luck to thank for that.
