         === Colts make sure Houston's luck continues to turn sour ===
 Indianapolis,  IN ( - Andrew Luck tossed a pair of touchdown
 passes  and the  Indianapolis Colts cruised to a 25-3 triumph over the reeling
 Houston Texans on Sunday at Lucas Oil Stadium.
 Luck completed 19-of-32 passes for 180 yards with an interception, while Trent
 Richardson  racked  up 102  yards from  scrimmage and a  touchdown for the AFC
 South champion Colts (9-5), who bounced back from an ugly 42-28 loss last week
 at Cincinnati.
 "I  don't think  we're that fickle where  we have to lose confidence like that
 after  a bad game," Luck said of coming off last week's setback. "Hopefully we
 can  get  a little mojo  going through  these next two  games. This was a good
 start against a good division team."
 The  turmoil with  the Texans,  who have  lost a  franchise-worst 12  straight
 games, reached a tipping point during the week leading up to Sunday's game, as
 head  coach Gary  Kubiak was fired after  eight seasons and a pair of division
 crowns.  Wade  Phillips, who  also handled  matters following Kubiak's medical
 scare on Nov. 3, took over on an interim basis.
 Despite  the change in leadership, the play on the field remained the same for
 Houston  (2-12), which  saw  quarterback Case  Keenum  complete just  18-of-34
 passes for 168 yards with a pair of interceptions.
 "I  was bad  today,"  Keenum admitted.  "My teammates  deserve  better and  my
 coaches deserve better."
 The  Colts'  opening drive set the  tone for the  entire tilt, as Luck led his
 squad  on an  11-play, 80-yard  sequence that  featured a  trio of  third-down
 Griff  Whalen capped  the trek with his  first NFL touchdown, hauling in a 14-
 yard strike from Luck to make it 7-0 just under 5 1/2 minutes into the game.
 Randy  Bullock buried a 49-yard field goal late in the first to get Houston on
 the  board, but Darius  Butler picked off Keenum two plays in the Texans' next
 touch and returned it 13 yards to the Houston 17.
 Indianapolis  failed to  pick up a first  down and settled for a 37-yard field
 goal  from Adam  Vinatieri, but  after another  Houston punt,  Luck threw  his
 second TD pass of the half to increase the Colts' cushion.
 T.Y.  Hilton highlighted  the drive  with a  41-yard reception  and Richardson
 capped it by hauling in a short pass and rumbling nine yards into the end zone
 to make it 17-3 with just over seven minutes left in the half.
 Butler  picked  off Keenum  again to  end the Texans'  next series, setting up
 Vinatieri's  43-yard field  goal that pushed the spread to 20-3 with 1:44 left
 in the half.
 The Colts carried their 17-point lead into the break and forced a quick three-
 and-out from Houston to open the second half.
 Whalen  returned  the Houston punt  51 yards to  the Texans' 28, and Vinatieri
 connected on a 40-yard field goal to make it 23-3 just over 2 1/2 minutes into
 the third.
 Indianapolis  extended  the  lead  late  in  the  stanza  when  Robert  Mathis
 blindsided Keenum in the end zone and knocked the ball free. Offensive lineman
 Duane  Brown pounced  on the  fumble, resulting  in a  safety that  pushed the
 difference to 25-3 with under two minutes left in the third.
 Mathis  recorded his  108th career sack on the play, surpassing Dwight Freeney
 for first place on the franchise's all-time list. His 16 1/2 sacks this season
 also broke Freeney's single-season franchise record set in 2004.
 Houston  failed to  get closer  than  the Indianapolis  41 over  the final  15
 minutes, allowing the Colts to close out the victory.
