Start:
Matt Scaub: The Jaguars defense is pretty good, but the strength of that unit is up front and not in the secondary. Last season in his two games vs. Jacksonville, Schaub totaled 567 yards, 3 TD/0 INT, and a 126.1 QB rating; no reason to think he can't have success again this year. The Texans won't be able to run for 219+ yards again this week, so Schaub will be asked to pass more and I believe he will deliver to the tune of 275-300 yards and 2 touchdowns.
Arian Foster: This may seem like a bad matchup for Foster, but I believe in the philosophy of NEVER sitting your star players unless they're hurt. Even if Foster doesn't put up 200+ total yards and 3 touchdowns again, he's still going to have a good day. I think his worst case scenario would be roughly 75 rushing yards, 30 receiving yards, and 1 touchdown; still a 17 point game. In his two games vs. the Jaguars last season, Foster rushed for 236 yards and3 touchdowns. The Jaguars defense isn't significantly better this season, he's definitely worth a start.
Andre Johnson: You'll just have to watch and wait. If he plays, he's a must start, but we likely won't know that until Sunday morning. So keep checking your fantasy sites, watch the NFL Network's pre-game show, and if he's announced as active; get him in your lineup.
Owen Daniels: Daniels has scored the seventh-most points at tight end this season as Schaub's 2nd option. This Sunday against the Jaguars, who have surrendered the seventh-most fantasy points to opposing tight ends this season, Daniels is a very nice start; a top 5 TE this weekend in my opinion. His TD drought is a little concerning, but if you're in a PPR league, Daniels is a no-brainer.
Neil Rackers: The Texans offense has been good enough to move the ball and put Rackers in range, but also poor enough in the redzone to give him opportunities. Rackers has attempted 2+ field goals in 4 out of his 6 games this season. Against a Jacksonville defense that will give up yards to the Texans but not touchdowns each trip, this looks to be a good matchup for Rackers. My prediction is 2 field goals and 3 XP's for Rackers on Sunday; a nice 9 point outing.
Texans Defense: The Texans are top 10 in rushing yards, passing yards, and points allowed, and tied for 4th in sacks; they've played really well this season. The Texans should have another decent shot at a shutout this week; they've come close twice before when allowing 7 points to the Colts and Titans. Against rookie QB Blaine Gabbert who's averaging just 130 yards passing a game with a 48% completion rate, the Texans have a really good shot at forcing turnovers and getting your team bonuses for points allowed and yards allowed. My prediction is 7-10 points allowed, 3 sacks, and at least 2 forced turnovers.
Sit:
Kevin Walter: He just isn't consistent enough, not to mention if Andre Johnson returns, Walter's targets will go way down. In the 4 games Andre has played this season, Walter has just 4 catches. Without Andre, Walter has 14 catches in 3 games; he's a decent bye week option in PPR leagues, but in any standard scoring league, he's a 3rd WR flex option at best. Even if Andre sits again, Daniels and Foster will probably have more targets than Walter.
