With veterans due to report to training camp this week, ESPN Stats & Information takes a look at the top stats to know for each team heading into camp. We'll begin with the AFC, with the NFC to come on Wednesday.
The Bills haven't been to the playoffs since 1999, the longest active drought in the league, but they might be inching closer. The 8-8 Bills finished at or above .500 for the second straight season after a 9-7 campaign in 2014 snapped a streak of nine straight losing seasons. The Bills posted a positive point differential in back-to-back seasons for the first time since 1998-99. The Bills' point differential totaled plus-127 over the last two seasons; during 2005-13, the Bills had a negative-627 point differential.
The Dolphins acquired cornerback Byron Maxwell and linebacker Kiko Alonso from the Eagles in exchange for a swap of first-round picks, with each addressing a major area of need. Miami gave up a franchise-record 31 passing touchdowns and over 2,000 yards rushing last season (2,019), its most since 2007. No team gave up more yards after contact per rush than Miami's 2.0.
The Patriots have used a league-low two starting quarterbacks since Tom Brady's first start in Week 3 of 2001. Brady's four-game suspension will end his streak of 14 consecutive season-opening starts, the longest among active QBs with their current team. Jimmy Garoppolo -- a 2014 second-round pick -- is the highest quarterback drafted by Bill Belichick in New England and most likely will be the Week 1 starter.
How long is the staring contest with free-agent quarterback Ryan Fitzpatrick going to last? Last season, Fitzpatrick set a Jets record with 31 passing touchdowns, and only Joe Namath in 1967 threw for more yards than Fitzpatrick (3,905) in team history. The 33-year-old Fitzpatrick remains unsigned, and the Jets drafted Christian Hackenberg with the 51st overall pick in April's draft.
The Ravens are hopeful of strong performances from two players whose 2015 seasons were shortened by injury. Quarterback Joe Flacco tore the ACL and MCL in his left knee in November, but even before the injury, he played poorly. His Total QBR of 40.9 was second worst in the NFL and a career low. The Ravens are also hoping to have back Steve Smith Sr., who tore his Achilles tendon in November. Smith is 39 receptions from 1,000 and 68 receiving yards from 14,000 for his career.
Andy Dalton set career highs in completion percentage, yards per attempt, touchdown-to-interception ratio and Total QBR last season. He ranked in the top five in the NFL in all but completion percentage (in which he was eighth). Among Dalton's top four pass-catchers at wide receiver and tight end last season, only A.J. Green is expected to be on the field with Dalton in Week 1: Marvin Jones and Mohamed Sanu signed elsewhere, and Tyler Eifert had ankle surgery.
The Browns will face Robert Griffin III's former division, the NFC East, in 2016 (home games against the Cowboys and Giants, road games against the Eagles and Redskins). Griffin was 5-1 against the NFC East in his rookie season, but he is 1-5 since. Only the Titans gave up more sacks last season (54) than the Browns (53). During 2012-14, Griffin was sacked on more than 8 percent of his dropbacks, the highest rate in the NFL (minimum 1,000 dropbacks).
Antonio Brown is coming off one of the most prolific receiving seasons in NFL history. Marvin Harrison is the only player in NFL history with more receptions in a season (143 in 2002) than Brown's 136 in 2015. The only players with more receiving yards in a season than Brown's 1,834 last season are Calvin Johnson (1,964 in 2012), Julio Jones (1,871 in 2015) and Jerry Rice (1,848 in 1995). Aside from Brown, quarterback Ben Roethlisberger will not be throwing to his most frequently targeted receivers from 2015. Martavis Bryant is suspended for 2016 and Heath Miller retired in the offseason. Pittsburgh signed Ladarius Green to replace Miller at tight end.
The Texans signed Brock Osweiler this offseason after starting four quarterbacks last season (Brian Hoyer, Ryan Mallett, T.J. Yates and Brandon Weeden). They became the first team in the Super Bowl era to reach the playoffs after four starters each won a game, according to Elias Sports Bureau research. The Texans gave Osweiler $32 million in guaranteed money after only seven career starts.
Andrew Luck and the Colts are looking to put the 2015 season behind them. The Colts won 11 games and went to the playoffs in each of Luck's first three seasons, but he missed more than half the 2015 season and Indianapolis missed the postseason. The Colts haven't missed the playoffs in consecutive seasons since 1997-98. Luck signed a six-year contract in the offseason that includes $87 million in guaranteed money, $17 million more guaranteed than any other player.
Blake Bortles set a franchise record with 35 passing touchdowns last season, 12 more than any other quarterback in Jaguars history. He also set team records in completions (355), attempts (606) and passing yards (4,428). Allen Robinson and Allen Hurns joined Jimmy Smith and Keenan McCardell (four times) as the only teammates in Jaguars history to each have 1,000 receiving yards in a season.
The Titans drafted Heisman Trophy winner Derrick Henry and traded for DeMarco Murray to headline the rushing attack. Tennessee running backs averaged 3.7 yards per carry last season, 29th in the NFL. Henry joins fellow Heisman winner, Marcus Mariota, whom the Titans drafted last season. The Titans became the first team to draft Heisman winners in back-to-back seasons since the Lions selected Barry Sanders in 1989 and Andre Ware in 1990.
Peyton Manning retired and Brock Osweiler signed with the Texans. The Broncos signed Mark Sanchez and drafted Paxton Lynch to fill the void at quarterback. Denver also selected Trevor Siemian in the seventh round of the 2015 draft. The last time a quarterback drafted in the seventh round started a season-opener for the team that drafted him was Tim Rattay, who started Week 1 for the San Francisco 49ers in 2004 and 2005, according to Elias Sports Bureau research. Elias also notes that the 2001 Ravens are the only defending Super Bowl champions to start a quarterback in Week 1 that was not on the roster during the championship season the year before. Trent Dilfer was Baltimore's Super Bowl XXXV quarterback, and Elvis Grbac started in Week 1 of 2001.
Jamaal Charles returns after suffering a torn ACL in his right knee in Week 5 of 2015. Charles is the all-time leader in yards per rush among players with at least 1,000 rush attempts. Over the past three seasons, no one has more combined rushing and receiving touchdowns than Charles' 38.
Derek Carr and Amari Cooper are both looking to build on an impressive 2015 season. Carr threw 32 touchdown passes, second most in a season in Raiders history (Daryle Lamonica, 34 in 1969), and his 53 touchdowns in his first two seasons are second most in NFL history (Dan Marino, 68). Carr needs 27 touchdown passes this season to become the fifth quarterback in NFL history with 80 touchdowns in his first three seasons. Cooper's 1,070 receiving yards last season set a Raiders rookie record and the fourth most by any rookie in the last 15 seasons.
The Chargers selected Joey Bosa with the third overall pick in the 2015 NFL Draft. Bosa had 50.5 tackles for loss, 26 sacks and five forced fumbles in 41 career games at Ohio State. Bosa had 101 total pressures in the last two seasons, most of any Power 5 player. The Chargers had 58 sacks in the last 2 seasons, second fewest in the NFL (Atlanta Falcons, 41).
