Titans coach Mike Vrabel believes Tennessee's running back duo will be a problem for opponents.The former linebacker refused to tip his hand when asked how he would defend Derrick Henry and Dion Lewis himself."I would have rather not tackled Derrick Arizona Cardinals Hats , and I would have rather not covered Dion" in the open field, said Vrabel, who played 14 years in the NFL.Vrabel made it clear that how the Titans divvy up the workload between the running backs will depend on how coaches want to attack each opponent. The 2015 Heisman Trophy winner , Henry brings a bruising style while displaying speed in the open field. The 5-foot-8 Lewis is much smaller next to the 6-3 Henry but flits around in open space making defenders miss."Man, I thought he was gone that one that he caught, like he was skating," Henry said of his new teammate. "But that's Dion. That's what he does: make people miss. He has quick feet and get him out in space he can be dangerous."As a first-year head coach, Vrabel and his new offensive coordinator Matt LaFleur have a pair of running backs that together could be the franchise's best duo since Chris Johnson and LenDale White combined for 2,001 yards in 2008. That season the Titans started 10-0 and finished with a league-best 13-3 record. The Titans' top two backs in 2009 combined for 2,287 yards with Johnson getting 2,006 himself.Henry backed up DeMarco Murray the past two seasons, though he led the Titans with 744 yards rushing last year despite starting only two games. He showed off his speed with a 75-yard touchdown run while also taking a pass 66 yards for another TD.Coming from Alabama where he left as the school's all-time leading rusher, Henry also has been very much a team player. Looking at Lewis, Henry said he thinks they can be very good together."We're two different styles of back like he's quick Black Andre Smith Jersey , he has good wiggle," Henry said. "He's good out of the backfield catching the ball and I'm downhill physical so I think we complement each other well."The Titans signed Lewis to a four-year deal in March after seeing the running back up close in their divisional playoff loss to the Patriots. Lewis ran 15 times for 62 yards and caught nine passes for 79 yards helping New England rout the Titans. For his career, Lewis averages 4.8 yards per carry with 10 TDs rushing, and he has five more TDs averaging 8.1 yards per reception.Lewis showed off just how elusive he can be in last weekend's 30-14 exhibition loss to Tampa Bay. He caught both passes thrown to him, taking one 16 yards. Marcus Mariota said Lewis makes it easy on quarterbacks with his body language and how the running back executes his routes."It causes a lot of problems for the defense," Mariota said. "Anytime you can have an advantage, you got to try exploit that as much as you can. Dion provides that for us, and you see once that guy gets the ball in his hands he's tough to tackle. Any which way that we can find to get him the ball is going to be beneficial for us."The Titans hope this running back tandem provides a boost in both the run and pass game. Tennessee slumped to 15th last season with 109.7 yards rushing and ranked just 23rd averaging 224.4 yards passing per game.Lewis knows exactly what he can do once he gets the ball in the open field."They brought me here to make plays in space and be the player I am, so whenever I get the opportunity to (do) that I just got to show my ability and be dependable," Lewis said.NOTES: The Titans made some roster moves, agreeing to terms with a trio of linebackers in Jeff Knox, Nyles Morgan and Deontae Skinner. They waived LB Brandon Chubb, LB Davond Dale and OL Matt Diaz.Follow Teresa M. Walker at teresamwalker TEMPE, Ariz. (AP) — When Arizona plays at the Los Angeles Chargers on Sunday Black Tre Boston Jersey , rookie Josh Rosen will make his eighth start at quarterback for the Cardinals. It's been a bumpy, up-and-down ride so far."I think he has been pretty good," coach Steve Wilks said. "I'd like for him to be a little bit more consistent. We all would, and he would probably tell you the same thing. The biggest thing is that we've got to make sure we limit the takeaways."Arizona is 2-5 with Rosen the starter. "I don't think that's good by anyone's standard," the 21-year-old quarterback said.Rosen's statistics aren't impressive. He's completed 55 percent of his passes for 1,416 yards and nine touchdowns, with 10 interceptions. In his last six games, he's thrown for seven TDs and was intercepted eight times. In Arizona's 23-21 home loss to Oakland last Sunday, Rosen threw for a career-best three touchdowns but was intercepted twice. Both interceptions led to Raiders touchdowns. Rosen completed only nine of 20 passes in the game for 136 yards, 59 of them on one play."Some of them are happenstance, " Wilks said of the interceptions, "but some of them could be just a lack of wanting to take the check down. He's trying to force things in there sometimes."Asked what he needs to improve, Rosen said "turnovers is a big thing, but just everything Black Benson Mayowa Jersey , being 100 percent of your checks, 100 percent of your reads. Just constant improvement in as many possible areas."Rosen, by nature, is an aggressive player and he acknowledges having to mitigate that with the willingness to check down and play things safe."There are certain kind of defensive positions where you can try and fit it in," he said. "So, if there's a zone dropping linebacker, there's no way you're going to get it around him, but if it's man coverage and the guy is kind of on his hip, that's something where you can give a guy a shot. …"But there are certain ones where I don't care how good you are, you're not going to get it complete. Depends on the play, the situation and defense."Rookie wide receiver Christian Kirk said people need to realize how much Rosen is being asked to do."He's got a lot on his plate. I think people forget about that," Kirk said. "But he does a great job in embracing it and I think every week he's just learning to take what the defenses gives him. He's a competitor. He wants to win. So at times he'll put a ball out there that's 50-50. Sometimes it doesn't go our way. But that's just him being a competitor."Seven games into the season, the Cardinals fired offensive coordinator Mike McCoy and replaced him with quarterbacks coach Byron Leftwich.It's the fifth offensive coordinator in four seasons for Rosen, going back to his early days at UCLA. Rosen praises what Leftwich has done for him."There's a lot of stuff within the offense that I didn't know Youth Mason Cole Jersey ," Rosen said. "It's an NFL offense. There are always going to be little things here and there. A lot more little tips on leverage and where guys are, which tells you what coverage you're going to get. So, there's a lot of disguise, but you're not allowed to disguise too good or otherwise you're going to be out of position. There are little tips and tells that I've been learning and picking up on."GONZALEZ IS BACK: Zane Gonzalez, the former All-American kicker at Arizona State who played just a little over one season with the Cleveland Browns, is back in Arizona on the Cardinals practice squad.He's seen as insurance for Phil Dawson, who has had some injury problems, as well as perhaps a kicker for the future for the Cardinals.Gonzalez is just glad to get the chance after being cut by the Browns two months ago. He said he's finally recovered from a recurring groin injury and didn't want to talk about his Cleveland experience on Wednesday."That's the past. I don't think about it anymore," he said. "I went back, I watched the tape. There's obviously a lot of issues with injury, amongst other things. I'm not the kind of guy who's going to go out there and make excuses. I took it on the chin for what it was and moved on. I think I earned a lot of respect from people back in Cleveland for that."
