Every NFL team goes into the draft with holes on the roster to fill. A statistical look at which teams did the best job of addressing their needs during the draft:
Buffalo Bills: Pass rush
Key loss: DE Mario Williams
• Williams led the Bills or tied for the team lead in sacks in each of the past four seasons.
• The Bills and Falcons are the only two teams without a player under contract who had more than five sacks last season.
• In the first season under Rex Ryan (and one year after posting a league-best 54 sacks), the Bills recorded 21 sacks -- second-fewest in the league.
• Lawson tied for fifth in the FBS with 12.5 sacks last season (second in the ACC).
• Striker is one of only two players in the FBS with at least 6.5 sacks in each of the last three seasons. (Michigan State DE Shilique Calhoun is the other.)
Pittsburgh Steelers: Defensive back
• The Steelers have allowed 4,000 passing yards twice in franchise history -- each of the past two seasons.
• The Steelers secondary allowed a 65.6 completion percentage when opposing quarterbacks targeted wide receivers, worst in the AFC and third-worst in the league. They allowed the most pass yards (3,100) to wide receivers last season.
• The Steelers spent their first two picks on defensive backs. Burns (25th overall), the first Pittsburgh DB taken in the first round since Troy Polamalu in 2003, led the ACC with six interceptions last year. Davis played safety at Maryland in 2013-14 and cornerback in 2015.
Indianapolis Colts: Offensive line
Key losses: None
• The Colts have gone 50 straight games without a 100-yard rusher, the longest streak since the Bengals from 1992-97 (67 straight games).
• The Colts averaged 3.5 yards per rush outside the tackles, a half-yard lower than any other team in the AFC.
• Colts running backs averaged 3.54 yards per rush last year, third-worst in the league.
• The Colts drafted four offensive linemen, Indy's most in a single draft since 1983. Alabama's Kelly was the 18th overall pick. He was the 2015 Rimington Trophy winner as the nation's best center, a consensus All-American and the Jacobs Blocking Trophy winner. He finished his career with 36 starts in 46 games and blocked for 26 100-yard rushers.
Tennessee Titans: Offensive line
Key losses: OL Joe Looney, OT Jamon Meredith
• Titans quarterbacks were sacked an NFL-high 54 times last year. Since sacks became official in 1982, two of the four highest sack totals in Oilers/Titans history were in the past two seasons.
• The Titans were one of three teams in the league to average 3.5 yards per rush or fewer inside the tackles (Chargers, Patriots).
• Jones, who made his NFL debut in 2012, hasn't missed a game.
bull; The Titans drafted Michigan State's Conklin eighth overall and Arkansas' Tretola in the sixth round.
• Conklin made 38 career starts and was the first Spartans offensive tackle to be named an All-American since 1997. He was the highest-drafted Michigan State offensive lineman since Tony Mandarich in 1989.
Philadelphia Eagles: QB/RB/OL
• The Eagles ranked 30th in Total QBR last season (41.5) and missed the playoffs despite being the NFL FPI preseason favorite from the NFC East. The Eagles drafted Wentz second overall.
• Eagles running backs were hit in the backfield 76 times last season, tied for second-most in the NFL. The Eagles spent their second pick on Oregon State's Seumalo (third round) and signed Wisniewski.
• After trading Murray, the Eagles are without their leading rusher from last season. Murray accounted for nearly half the team's rushes (45 percent) on first and second down. The Eagles used their third pick on Smallwood (fifth round). Including Smallwood, the past five RBs drafted by the Eagles have been in the fifth round or later.
Detroit Lions: Offensive line
Key losses: G Manny Ramirez
• Matthew Stafford has been sacked 89 times the past two seasons, fourth-most in the NFL.
• Stafford has taken 40 or more sacks in each of the past two seasons. He took no more than 36 sacks in any of his first five NFL seasons.
• Detroit spent the 16th pick on Ohio State's Decker and the 95th pick on Michigan's Glasgow. Decker was the 2015 Big Ten Offensive Lineman of the Year. Ohio State averaged 7.4 yards per rush outside its left tackle, best in the Big Ten (6.1 outside RT).
Seattle Seahawks: Offensive, defensive line
• The Seahawks have allowed pressure on 37 percent of opponent dropbacks since 2012, highest in the NFL. The Seahawks have finished with the highest or second-highest percentage each year in that time.
• Okung left, and the Seahawks spent their first draft pick on Texas A&M's Ifedi (first round). Ifedi was a three-year starter at Texas A&M, primarily at right tackle.
• The Seahawks have been losing depth across the defensive line since their Super Bowl-winning season. Mebane, one of the four linemen to play 40 percent of Seattle's defensive snaps last season, departed as a free agent.
• They used their second pick on Alabama's Reed. On designed rushes inside the tackles, Alabama ranked second among Power 5 teams in yards per rush allowed (3.1) and yards after contact per rush allowed (1.4).
