Who's filling the biggest needs for all 32 NFL teams

— -- The Panthers have to find a replacement for cornerback Josh Norman. A third-year nose tackle will take over for the Steelers. The Redskins are getting back a pass-rusher who missed the entire 2015 season. NFL Nation reporters choose the player who will fill the biggest need for every team.

AFC EAST

Buffalo Bills: Linebacker  Zach Brown  is new to the Bills, signing as a low-cost free agent in March. The former second-round pick is expected to replace speedy linebacker Nigel Bradham in sub packages. General manager Doug Whaley has spoken about the importance of speed at linebacker to defend tight ends such as  Rob Gronkowski and Martellus Bennett in the AFC East, and Brown is the best option among a relatively thin Bills inside-linebacker group. -- Mike Rodak

AFC NORTH

Baltimore Ravens: The Ravens didn't sign a free-agent inside linebacker or draft one after releasing leading tackler Daryl Smith this offseason. That leaves a hole in the middle of the defense. Zachary Orr is considered a favorite to win that spot next to C.J. Mosley, based on his increased playing time at the end of last season. But Orr will be competing against Arthur Brown, a slow-developing second-round pick from 2013, and Kamalei Correa, a rookie second-round pick who had been projected to play on the outside. The Ravens also could add a veteran inside linebacker before training camp. -- Jamison Hensley

AFC SOUTH

Houston Texans: The Texans allowed starting defensive end Jared Crick to leave in free agency and then neither signed a defensive end in free agency nor drafted one. One player who could fill that need is Devon Still , whom the Texans signed to a futures deal back in January. Still, famously the father of cancer survivor Leah Still, was a defensive tackle in Cincinnati, but would fit as a defensive end in the Texans' system. He's making good use of the resources he has in Houston, too. "Devon asks a lot of questions," said J.J. Watt, the Texans' other defensive end. "He really wants to get a good grip of the defense." -- Tania Ganguli

AFC WEST

Denver Broncos: If the Broncos' plan to regulate DeMarcus Ware's snap count this season is to work to the fullest extent, outside linebacker Shane Ray has to be ready to go from touted prospect to a reliable option. The Broncos' plan is to use Ware, who has missed a large portion of the on-field work in the offseason program because of back troubles, in mostly a pass-rush role this season, but to do that Ray has to be ready to go from spot duty to more significant action. The Broncos and Ware agreed to a pay cut this offseason with the prospect of having more of a specialist role. Ray has to be ready to make that change in philosophy work. -- Jeff Legwold

NFC EAST

Dallas Cowboys: Pass rush has been and will be the Cowboys' biggest need as it is for a lot of teams, but the Cowboys' issue is more acute with the four-game suspension facing Randy Gregory and the looming penalty for DeMarcus Lawrence. Because they play defensive end, most of the focus has been on that spot, but the Cowboys will take pass rush from anywhere. Tyrone Crawford is going into his fifth season, but he missed the 2013 season with a torn Achilles and was moved to defensive tackle in 2014 where he thrived, resulting in a $45 million extension. He had a career-high five sacks last year but the Cowboys believe he can have more of an impact as an interior pass-rusher. They have floated the possibility of having him play some defensive end early in the season, though his strength is as an interior pass-rusher. -- Todd Archer

NFC NORTH

Chicago Bears: With  Martellus Bennett gone to New England,  Zach Miller  is responsible for filling the void at tight end. Bennett is a Pro Bowl-caliber talent, but Miller, when healthy, is equally dynamic. After starting a career-high 14 games in 2015, Miller is trying to pick up where he left off. He is full-go in the Bears' offseason program, and next to Kevin White and the absent Alshon Jeffery, Miller is expected to be one of the team's top weapons in 2016. An added bonus is that Miller already has chemistry with quarterback  Jay Cutler. If he can just avoid injuries, Miller is talented enough to put up big numbers. -- Jeff Dickerson

NFC SOUTH

Atlanta Falcons: The Falcons sorely need a pass-rusher to step up and become a dominant force. Vic Beasley Jr. has to be that guy in his second season. Much is being made about Beasley's move to Sam linebacker and how that will force him to drop into coverage. True, Beasley might have those responsibilities at times, but his primary role will be to rush the passer. He'll be a nickel rusher and he'll probably be utilized as a blitzer as well from his Sam spot. Beasley had a team-leading four sacks last season, but that wasn't nearly enough for a team that finished last in the league with 19 sacks. He is capable of notching double-digit sacks and moving the quarterback off the spot, provided Beasley adds some counter moves to his outstanding speed off the edge. -- Vaughn McClure

NFC WEST

Arizona Cardinals: Once the Cardinals lost cornerback Jerraud Powers to free agency, they were left with an inexperienced option in Justin Bethel to take over his role full time. As of now, Bethel seems like the most likely option to become a full-time starter next in 2016, but don't count out three other possibilities: rookies Brandon Williams and Harlan Miller, as well as Cariel Brooks. -- Josh Weinfuss
