HOUSTON -- Yes, the Houston Texans have the last-ranked offense in the NFL in terms of scoring, total offense and rushing offense.No, that doesnt mean the Texans are planning to take away play-calling duties from offensive coordinator Tim Kelly.Texans coach David Culley backed Kelly, affirming his responsibilities and stating that he isnt to blame for the offensive woes.In his second year as Texans offensive coordinator, Kelly has overseen an offense thats averaging a league-low 14.9 points and 264.8 yards per game, Manny Ramirez Jersey while also ranking last in rushing offense and average per carry.Kelly, 35, was retained after the Texans fired former coach/general manager Bill OBrien. Houston had NFL pa sing leader last season in Pro Bowl quarterback Deshaun Watson. Of course, Watson isnt playing after requesting a trade and is facing unresolved legal i sues. And the Texans are playing without Mike Napoli Jersey injured offensive linemen Laremy Tunsil, Marcus Cannon and Justin Britt.Thats not even a question about Tim being the play-caller, Culley said Monday at NRG Stadium. We got to play better. It has nothing to do with the play call. It has something to do with us playing better and doing things the right way.The Texans squandered a 14-11 halftime lead Sunday during a 21-14 lo s to the New York Jets, and had just three first downs and 45 yards of total offense in the second half.The Texans have struggled to run and football, but have improved lately in avoiding turnovers. Overall, though, this is far from a Larry Doby Jersey dangerous offense.Scroll to ContinueNo, I would just like to see our whole offense do better, me as a head coach do better in getting things the way it should be, Culley said. But no, there is no question about our play-calling. Its the fact that we are not doing what we need to do when the play is called.The Texans allowed five sacks against a disruptive Jets front seven headlined by John Franklin-Myers (two sacks, one interception) and Matt Belisle Jersey Quinnen Williams.It was tough sledding again for the running game.Well it has something to do with everybody on the offense, Culley said. The line, when the backs arent always hitting the right hole, we arent always making the right calls. Its a combination of things. Its not who is running the ball. Its how we are all executing it when we are out there running those plays..After quarterback Tyrod Taylor threw touchdown pa ses to receiver Brandin Cooks and rookie tight end Brevin Jordan to build a 14-3 lead, the offense nosedived.The Texans finished with just 13 first downs, 202 yards of total offense and an average of 3.7 yards per offensive play.The Jets entered Sunday allowing 414.2 total yards of offense and 282.2 pa sing yards per game. The flow wasn't right in the second half, Taylor said. We have to be better at that moving forward. I think that boils down to execution."If you look at the first half, the flow of the game was in our favor Trevor Bauer Jersey . We were executing, hitting our chunk plays, doing what we needed to do in the run game. We didn't do it in the second half.
