The NFL certainly has shifted to a pa s-happy approach over the past decade. With each pa sing year, teams are putting the ball in the air more and more, and a host of explosive playmakers are dominating the game from the perimeter. Thus, having a top-tier group of pa s catchers is more advantageous than ever.So who has this luxury? Now Matthew Dellavedova Jersey that the bulk of free agency is over and the 2015 is in the rearview, it's a great time to re-a se s which NFL teams boast the top groups in this area.After thinking about how rookies will fit into their new teams and reviewing from last season, I've come up with five receiving units (tight ends included) that stand out above the rest. Here's how I would rank them heading into training camp:1) Green Bay PackersCredit general manager Ted Thompson and head coach Mike McCarthy for taking a homegrown approach to a sembling the most complete aerial attack in the NFL. The have systematically drafted and developed each of the key contributors to the pa sing game, a fact that is e sential to maintaining long-term consistency in the salary-cap era. The team has transformed a pair of exceptional return specialists ( and , both second-round picks) into a dynamic WR tandem that racked up 2,806 combined receiving yards and 25 touchdowns in 2014. Granted, the spectacular performance of the NFL's MVP (quarterback ) fueled the jaw-dropping production. Still, astute observers recognize the special traits that Nelson (a precise route runner with big-play ability) and Cobb (a super-quick slot receiver with electric running skills) bring to the field. In the ' highly efficient dink-and-dunk system, Nelson and Cobb terrorize opponents on a variety of catch-and-run plays on the perimeter.With Nelson and Cobb -- who each earned recognition as Green Bay's top two wideouts -- producing like that, it's easy to overlook the supporting cast of receiver and tight ends and . But those three add athleticism and versatility to the lineup, allowing the to use a variety of personnel groupings and exotic formations to exploit mismatches on the perimeter. Rookie is a wild card for Green Bay as a receiver/return specialist. Taken in the third round earlier this month, the Stanford product is dynamic with the ball in his hands, but he must show better consistency to crack a spot in this deep rotation.2) Denver BroncosDespite the lo ses of , and over the past two offseasons, the still field one of the most explosive receiving units in the NFL. Led by and , the attack opponents with a variety of bubble screens, short cro sers and vertical routes on the perimeter. New head coach Gary Kubiak will tweak the heavy reliance on "now" throws in the game plan, but the shift to a play action-based vertical D.J. Augustin Jersey pa sing game should allow Thomas and Sanders to continue to put up big numbers. Denver's dynamic duo likely will run more deep overs, comebacks and stutter routes on the perimeter, which will lead to fewer touches (Thomas and Sanders accounted for 212 receptions for 3,023 receiving yards and 20 TDs in 2014) but a higher yield (increased yards-per-catch figures) in a pa sing game built on run-action deception in the backfield. Lastly, , the ' second-round pick in 2014, could be in for a breakthrough sophomore campaign.With Kubiak poised to feature more tight end-friendly concepts to work the middle of the field, don't sleep on and . Daniels, in particular, could form a nice connection with . The two-time er is adept at finding creases between the hashes and is fresh off a solid season as the TE1 in Baltimore. He should join Green in the ' "12" personnel package to create an effective inside-outside attack in the pa sing game.3) Indianapolis ColtsThe have a sembled a solid nucleus in the pa sing game that ranks among the best in the NFL. After snatching with the first overall pick in 2012, GM Ryan Grigson wisely selected (Round 2), (Round 3) and (Round 3) in that same draft, to grow along with the franchise quarterback in his developmental years. And of course, this group has played a big part in Indy's three straight playoff berths and two straight AFC South titles.Hilton has blo somed into one of the NFL's most explosive playmakers on the perimeter, with a total of 17 catches of 40-plus yards in his brief career. Moreover, he has posted back-to-back 1,000-yard seasons and a sumed the role of WR1 in the offense. Meanwhile, Fleener and Allen quietly have become one of the league's most effective tight end tandems. They each scored eight touchdowns in 2014, terrorizing opponents with their contrasting styles (Fleener is the athletic "move" tight end adept at vertical routes; Allen is the big-bodied playmaker ideally suited to win in third-down/red-zone situations). There are few defenses capable of shutting down a dominant 1-2 punch between the hashes.And the challenge of defending the ' pa sing game will be made even tougher by the addition of and the continued development of . Johnson gives the a big-bodied pa s catcher with a pedigree on the perimeter. Although he has lost a step, Johnson remains a viable threat and should alleviate the pre sure on Hilton to carry the Jon McGlocklin Jersey load as the WR1. First-round pick could be the ultimate X-factor for Indy. As an explosive deep threat with speed to burn, he could make a number of plays down the field.Long story short, the seemingly have an answer for every defensive tactic an opponent can throw at their diverse aerial attack.4) Detroit LionsWhenever a team trots out one of the most dominant pa s catchers in football, defensive coordinators around the NFL can't help but sweat -- especially when that explosive playmaker is a 6-foot-5, 236-pound freak with a rare combination of size, speed and ball skills.Thus, it shouldn't come as a surprise to see the ranked on this list, largely due to . The perennial er can single-handedly take over a game with his overwhelming physical stature -- and he's also become a more complete playmaker throughout his career. He's significantly improved as a route runner, yet remains a jump-ball specialist capable of wrestling 50-50 balls away from multiple defenders in the red zone. Johnson's mere presence on the perimeter commands double coverage, freeing up the field for his supporting cast. showed with he could do in his first season with Detroit, posting team highs in catches (99) and yards (1,331). The slick pa s catcher is arguably one of the best playmakers in football, exhibiting exceptional running ability and ball skills. He carried the during Johnson's three-game absence due to injury (Tate ama sed two of his five 100-yard games during that stretch) and anchored the pa sing game until was ready to resume duties as the WR1. Most importantly, Tate emerged as an effective complement to Johnson, giving the a dominant 1-2 punch., and failed to post big numbers in 2014, but the tight end position should play a bigger role in coordinator Joe Lombardi's offense this season. I'm particularly intrigued by Ebron, who could make a substantial jump in Year 2 of his career. Honestly, that's a big part of why Detroit got a spot on this list -- I expect big-time growth from the sophomore TE.5) New York GiantsConsidering Big Blue's blue-collar reputation, it feels a little weird to include this team on a list of the most Eric Bledsoe Jersey dynamic aerial attacks in football. But GM Jerry Reese has a sembled a cast of pa s catchers that could take the league by storm in 2015.Led by 2014 Offensive Rookie of the Year Jr., the G-Men have the firepower to overwhelm opponents with a high-flying pa sing game this fall. The 5-11, 198-pound playmaker is arguably the most spectacular young receiver in the NFL, with a game that is polished well beyond his experience. From his superb route-running ability to his unbelievable ball skills, Beckham is a legitimate WR1 with extraordinary big-play ability. He is a rare pa s catcher capable of stretching the field on vertical routes or delivering home runs on an a sortment of catch-and-run plays. is coming back from a . Before the injury, he was the most explosive slot receiver in the game. Here's hoping he can return to form in 2015. When healthy, he exhibits rare stop-start quickne s between the hashes, which makes him nearly indefensible in one-on-one matchups. In the ' quick-rhythm offense, which features a host of slants from the slot, Cruz wears out nickel corners, linebackers and safeties in the middle of the field. Cruz is also capable of racking up big yardage on the outside as a traditional "Z" or "X", but the can put opponents in quite a bind when aligning their top receivers on the same side. If Cruz returns to form this season, New York's pa sing game could be downright scary to defend.Receiver and tight end round out the unit as complementary players. Each is capable of winning one-on-one matchups against CB3s and CB4s, which makes Khris Middleton Jersey the ' offense problematic to defend when offensive coordinator Ben McAdoo elects to open up the formation with three-receiver sets. Donnell just enjoyed a breakout season with 63 catches for 623 yards and six touchdowns. He could emerge as a dominant red-zone weapon in 2015 and beyond.Follow Bucky Brooks on Twitter .
