TEMPE Devin Singletary Jersey , Ariz. — Arizona Cardinals offense.Whether Byron Leftwich can awaken that slumbering unit remains to be seen.But Arians’ influence is undeniable.After a lot of lobbying, Arians talked Leftwich into taking a job as a coaching intern two seasons ago. Last year, he promoted Leftwich to quarterbacks coach.When Arians retired as Cardinals head coach after last season and Steve Wilks was hired, Leftwich stayed on as quarterbacks coach. And when Wilks fired Mike McCoy last week, Leftwich was promoted to offensive coordinator.“B.A., he’s the reason I’m here,” Leftwich said Thursday in his first meeting with reporters since getting the new job. “It was just special that he gave me this opportunity. He’s been trying to get me to do it forever and he gave me the opportunity and once I saw it I fell in love with it.“He knew the way I cared about football. He knew how much time and energy I put into this thing. I’m glad he got me into this thing because I love every minute of it right now.”Rookie quarterback Josh Rosen sees the Arians influence.“Byron is sort of a B.A. descendant, and he (Arians) is sort of a ghostly legend in this building here,” Rosen said. “I think he’s putting in some new stuff but also pulling on some past knowledge. I am looking forward to what we are about to do with him.”Leftwich, like Rosen, was a first-round draft pick at quarterback Kyler Murray Jersey , chosen seventh overall out of Marshall by Jacksonville in 2003. He played 10 seasons in the NFL, the last three with Pittsburgh. Arians was the Steelers‘ offensive coordinator for two of those seasons, and they developed a bond that continues to this day.When he finally convinced Leftwich to take a coaching job, Arians let him call plays last year for a pair of preseason games.“He was outstanding,” Arians said in an interview on Arizona Sports 98.7 FM. “He was always a play ahead. You could tell he was a quarterback and a really, really smart one. He had such a great rapport in that room. I know Carson Palmer leaned on him heavily.”Leftwich inherits an offense that ranks last in the NFL in total yards and yards rushing and next-to-last in yards passing. Just what alterations he can make for Sunday’s game against San Francisco is uncertain.“It’s tough to change a lot in a week but there is things that we can do,” Leftwich said. “It’s not really about doing a bunch of different stuff. It’s about getting these guys. It’s about Josh, it’s about the growth of Josh but it’s about the other 10 guys also. We’ve just got to play better and we’ve got to practice better.”His main focus is the development of Rosen.“I mean he’s a young quarterback. This kid’s 21 years old. This is the National Football League,” Leftwich said. “I’ve been there. I know what he’s going through. I know what he’s thinking. We’re just trying to get him there, get him there as quickly as possible, getting him there as safe as possible and just teach him the things that he’s going to need to play consistently for a long time in this league.”Leftwich said his playing career mirrored that of Rosen in the early years.“I really like this kid http://www.billscheapshop.com/cheap-authentic-dawson-knox-jersey ,” he said. “I think this kid can really play football.”Leftwich is Rosen’s fifth offensive coordinator in the past four years.“It’s not fun. If I could prefer it, I would have one offense, but that’s not really how it all worked out,” Rosen said. “So, I’m just going to do the best I can with what I’ve got.”But Leftwich said he’s not throwing a lot of new material at Rosen.“I’m not changing this thing up,” he said. “I’m not going to put this kid in a situation where he’s out there and doesn’t have an understanding of what he’s doing. I’m just trying to give him a better understanding of what he’s doing, just put him in better positions so he can have a lot of success in this league.”Arians, in his radio interview, had one prediction for the Leftwich offense.“One thing I’ll bet,” Arians said. “It’s a very teachable game plan and the guys will know exactly what’s expected of them.” BUFFALO BILLS (6-10)UNRESTRICTED FREE AGENTS: WR Deonte Thompson, OGs Ryan Groy and John Miller http://www.giantsauthorizedshops.com/authentic-dexter-lawrence-jersey , OT Jordan Mills, RB Taiwan Jones, DT Kyle Williams (retired), CB Vontae Davis (retired).RESTRICTED FREE AGENTS: TE Logan Thomas, CB Lafayette Pitts, DL Eddie Yarbrough, LB Deon Lacey, P Matt Darr.NEEDS: With their quarterback position finally (hopefully?) settled following Josh Allen’s rookie season, Bills can begin filling various needs around him. And after spending past two years purging high-priced and underachieving players, they also have money to spend, though GM Brandon Beane maintains he’ll be “judicious.” It starts with upgrading patchwork offensive line that was unable to offset abrupt losses of C Eric Wood (career-ending injury) and LG Richie Incognito (retirement) in 2018. Buffalo has begun adding linemen after signing Spencer Long to three-year contract last month. Receiver is another issue after Kelvin Benjamin’s production deteriorated — he was cut with month left in season. Bills added to offense by agreeing to sign RB Frank Gore and TE Tyler Kroft. Gore http://www.arizonacardinalsteamonline.com/zach-allen-jersey , 35, joins 30-year-old LeSean McCoy to form NFL’s oldest backfield tandem. Kroft joins team that was carrying one tight end, Jason Croom. On defense, Buffalo’s thin at linebacker. With starting job open opposite Tre’Davious White, Bills reached agreement to sign former Texans cornerback Kevin Johnson.AVAILABLE SALARY CAP SPACE (approximately): $70.6 million, though the anticipation is Bills will target mid-range free agents and avoid making splash they did in signing DE Mario Williams to six-year, $100 million contract seven years ago.
