Recapping Day 1 of free agency: Texans, Giants score big

— -- NFL Nation reporters break down the opening day of free agency for all 32 teams:

AFC EAST

Buffalo Bills: The Bills were quiet Wednesday and aren't expected to be active for the rest of the week. They have only about $4.5 million in cap space, the result of both their big spending last offseason and their ability to get their top free agents -- defensive tackle  Marcell Dareus and offensive linemen  Cordy Glenn and Richie Incognito -- under contract prior to Wednesday. -- Mike Rodak

AFC NORTH

Baltimore Ravens: The Ravens officially reached an agreement with Saints tight end Benjamin Watson on a two-year, $8 million deal ($3 million guaranteed), which is an indication that Baltimore is concerned about the availability of Crockett Gillmore, who had surgery on both shoulders this offseason. Baltimore placed a second-round tender on wide receiver Kamar Aiken, who topped the team in receiving last season. The Ravens created cap room by restructuring the contract of guard Marshal Yanda and reducing the base salary of cornerback Kyle Arrington.  -- Jamison Hensley

AFC SOUTH

Houston Texans: What an opening day for the Texans. Minutes before the league year opened, they secured deals with quarterback Brock Osweiler, running back Lamar Miller and offensive lineman Jeff Allen. All three are designed to help revamp a Texans offense that was bad last season. There are still plenty of needs remaining, but the Texans invested a lot in their opening-day moves, committing $126 million over four years to the three players. -- Tania Ganguli

AFC WEST

Denver Broncos: It was a tough opening day of the new league year for the Broncos as they watched defensive end Malik Jackson and quarterback Brock Osweiler get the love of the open market. Jackson's departure can be more easily addressed in a draft deep in defensive linemen, but the Broncos' depth chart at quarterback now consists of only  Trevor Siemian and will likely need a combination of the draft and free agency to fill it in. -- Jeff Legwold

NFC EAST

Dallas Cowboys: The Cowboys opened free agency the way they said they would: quietly. They were able to retain linebacker Rolando McClain on a one-year deal, and they have upcoming visits with Cedric Thornton and Matt Moore, but they were not going to shell out big money for running backs or get into the top end of the market for cornerbacks and pass-rushers. They will let the market come to them and hope to find pieces to supplement the roster. It angers some fans, but big spending isn't the only answer either. -- Todd Archer

NFC NORTH

Chicago Bears: The Bears were quiet leading up to the official start of free agency, but the team struck quickly, agreeing to multiyear contracts with inside linebacker Danny Trevathan, right tackle Bobby Massie and cornerback Tracy Porter. Trevathan is by far the biggest catch, and at 25 years old should anchor the middle of Chicago's defense for many years. The acquisition of Massie is intriguing because it could trigger Pro Bowler Kyle Long moving back to right guard. The Bears wanted Porter back after he led the club with 22 pass breakups in 2015. Chicago also signed running back Jacquizz Rodgers and offensive tackle Nick Becton to one-year deals. -- Jeff Dickerson

NFC SOUTH

Atlanta Falcons: The Falcons landed arguably the best offensive lineman on the market in three-time Pro Bowl center  Alex Mack, who agreed to a five-year contract reportedly worth more than $9 million per season. Matt Ryan needed a stable force in front of him, and Mack has the athleticism to thrive in the outside zone blocking scheme. The other moves were adding veteran signal-caller  Matt Schaub, originally drafted by the Falcons, to back up Ryan, and former Dolphins defensive end Derrick Shelby, who agreed to a four-year deal.  -- Vaughn McClure

NFC WEST

Arizona Cardinals: It was expected that the Cardinals would be relatively quiet on the first day of free agency, and they lived up to that billing. They reportedly signed safety  Tyvon Branch to a two-year deal worth as much as $10 million. They  did not re-sign right tackle  Bobby Massie, who agreed to a three-year contract with the Bears. -- Josh Weinfuss
