A look at the Colts' Week 5 opponent: Houston Texans

INDIANAPOLIS -- The Indianapolis Colts are supposed to have a lot of success this season based off their schedule.

On paper, that is.

Yes, they play in the AFC South, one of the worst, if not the worst, divisions in the NFL. They also play the NFC South, which had a team with a losing record -- the Carolina Panthers -- make the playoffs last season, and the AFC East, which only had the New England Patriots make the playoffs last season.

But each season brings changes to rosters.

We're going to take a look at the Colts' week-by-week opponent for the 2015 season.

Today we take a look at the Houston Texans

2014 record: 9-7

First-round draft pick: CB Kevin Johnson

Veteran additions: QB Brian Hoyer, WR Cecil Shorts III, RB Chris Polk, WR Nate Washington, S Rahim Moore, S Stevie Brown, DT Vince Wilfork

Veteran subtractions: WR Andre Johnson, OLB Brooks Reed, C Chris Myers, S Danieal Manning, DT Jerrell Powe, S Kendrick Lewis, DT Ryan Pickett, QB Thad Lewis, DE Tim Jamison, QB Case Keenum, QB Ryan Fitzpatrick, WR DeVier Posey, S Josh Aubrey, DE Keith Browner

Area of concern for the Colts: J.J. Watt. The do-everything defensive end is a problem for every offense in the NFL because he can beat teams in a number of different ways. Watt had 13 tackles, four sacks, four passes defended and a touchdown in two meetings against the Colts last season. And now Watt will have more help on defense with him this season. The Texans signed former New England defensive tackle Vince Wilfork to anchor the middle of the defensive line. Defensive end Jadeveon Clowney, the No. 1 overall pick in the 2014 draft, will back and Houston selected cornerback Kevin Johnson in the first round of this year's draft.

Area that favors the Colts: The Texans defense will be tough to score on and they also have Arian Foster (104 yards a game rushing in two meetings against Indy last season) at running back, but questions still remain about their quarterback situation. The Texans signed journeyman Brian Hoyer to compete with Ryan Mallett for the starting job. You have to have a quarterback to be successful in the NFL. The Texans, as the case has been for them for quite some time, still have uncertainty at quarterback.
