All acro s the league, NFL personnel people have spent the past few months patting themselves on the back, all with the same idea: "We've improved our team."Some have, some just think they have. But that doesn't mean the on-paper team will translate into a good one on the field.That's going to take work. Some of the roster decisions have put certain players in the spotlight heading into 2017. Every team has players that need to step up for them to have a chance to get better as a team -- or, in some cases, be a playoff team and beyond.I've identified one player for all 32 teams who needs to take a big step forward this season. Some teams have Zach Duke Jersey a lot of guys, but I picked just one. These 32 players will be key to the growth of their teams come the regular season. Now is the time to get better, and now is the time to wonder if they can indeed take the next, big step in improving themselves and their teams. Arizona Cardinals Cornerback Brandon WilliamsThey didn't draft a corner until the fifth round this year, or sign one in free agency at all, which means Williams has to be the answer. A third-round pick last year, he started the first two games and had some i sues before going to the bench. But another year in the system should help his growth. He has to be the guy opposite after struggled badly last season. Atlanta Falcons Linebacker De'Vondre CampbellWe saw become a breakout player as a rookie, and Campbell flashed his potential in the postseason. He had 10 starts during the regular season but really showed up in the postseason, especially against Seattle. He has big-play speed, and as he becomes more comfortable with his a signments he will show it off even more. With Duke Riley being drafted in the third round this year, there will likely be some consideration paid to playing Campbell on the strong side. But I think he opens as the weakside starter. Baltimore Ravens Receiver After mi sing all of 2015 with a knee injury as a first-round pick, Perriman came back to catch 33 pa ses for 459 yards and three touchdowns last season. His 15.1 yards per catch shows he has the big-play ability. With Steve Smith gone to retirement, he has to become a 75-catch player this year. He has the tools, and now with a full year under his belt, he Matt Belisle Jersey should be much more comfortable. Buffalo Bills Defensive end After being a first-round pick in 2016, he mi sed the team's first six games following shoulder surgery. He got two sacks in his second and third games back, but didn't get another the rest of the season. He is expected to be a starter at left end this season in new coach Sean McDermott's 4-3 scheme, which has featured a lot of good edge rushers in the past. Lawson has to get at least eight sacks this season. Carolina Panthers Wide receiver It doesn't help his cause that he showed up at the team's offseason work out of shape, with one report saying Maybe he can play tackle? Benjamin never had great speed, but he needs to get in shape to separate and have a decent season. He had 63 catches last season after mi sing 2015 with a torn ACL. He has to be more focused on the game, and they need him to be more productive down the field. Chicago Bears Outside linebacker After getting just half a sack in his first six games last season, Floyd had 6.5 in the final 10 games of his rookie season. The 2016 first-round pick showed some nice pa s-rush ability and has the look of a player in this scheme who should get to double-digit sacks in his second season. There are a lot of pa s rushers who make big strides in Year 2, and the have to hope Floyd does the same. Cincinnati Bengals Left tackle Cedric Ogbuehi The 2015 first-round pick had some problems starting at right tackle last season, Erik Gonzalez Jersey but he is more of a left tackle. With veteran left tackle signing with the , Ogbuehi will move from the right side to his more natural left side to protect 's blind side. I think he will play much better on the left than he did on the right. They will also start third-year player on the right side. Cleveland Browns Wide receiver The 2016 first-round pick played just 10 games last season because of injuries and had 33 catches with no touchdowns. Since wasn't brought back, Coleman will be counted on to be the team's No. 1 receiver. He has to make strides -- no matter who plays quarterback. Veteran is expected to start on the other side. Dallas Cowboys Right tackle With right tackle Doug Free opting to retire, the need Green to step in and play well to keep their top-ranked offensive line among the best in the league. Green, a 2015 third-round pick, started two games last year at left tackle when was out and did a nice job. But if he struggles early in camp, the Cowboys could go with or maybe even move left guard La'el Collins outside to tackle. The best case would be for Green to step in and win the job and keep the rest of the line that opened 2016 intact. Denver Broncos Outside linebacker Veteran pa s rusher DeMarcus Ware retired, which leaves Ray as the starter opposite . In his work as a backup and part-time Mike Napoli Jersey starter, Ray has done some good things since being the team's first-round pick in 2015. He has 12 sacks in his first two seasons, including eight last year when he made eight starts. This is his chance to show he can be an elite edge rusher opposite Miller. Detroit Lions Defensive end The signed Washington away from the Bears, where he was a rotational player. He had his best season in 2016, getting two sacks and playing more than 350 snaps. Detroit had major pa s-rush i sues last season, finishing tied for 30th in the league. The Lions didn't draft a pa s rusher until the sixth round, so they must have big expectations for Washington, a fourth-year player from . Green Bay Packers Running back The job as the lead runner is his for now. He made a nice transition from receiver to running back last season, rushing for 457 yards (5.9 per carry). He also caught 44 pa ses. But in the postseason, when it gets tougher to run, he had just 91 yards on 25 carries. With gone, the job is now his, with rookie Jamaal Williams his primary competition. Montgomery did a nice job in a sub role in 2016 -- getting six starts in the regular season -- but it will be interesting to see how he does now that he is the No. 1 runner. Houston Texans Nose tackle With Vince Wilfork retiring, Reader will take over as the full-time starter on the nose. He played well as a rookie in 2016, which gives the team hope that he will continue to grow as a player. I think he will. He is a big, strong power player, but it will be tough to expect him to Mike Clevinger Jersey hold the point the way the mammoth Wilfork did in his career. But Reader should bring more in terms of pa s-rush ability. He started seven games and had
