Now that OTAs are in full swing, we've reached a turning point in the NFL offseason. The off-field moves that have dominated the past few months -- the free-agent signings, trades and draft picks -- are giving way to honest-to-goodne s on-field action. As we leave the transaction-heavy portion of the offseason behind, I thought I'd review all the wheeling and dealing to see which teams have been most productive.Below is my list of the six teams that have had the best offseasons, with five more to consider at the end for good measure:1) New York JetsKey additions: CB , DT , offensive coordinator Chan Gailey.When you add one Tremaine Edmunds Jersey of the best cornerbacks in the NFL and the best defensive lineman in the draft, you know you've had a good offseason. The in overall defense last season but ; Revis, , and will improve what was considered a weak secondary last year. Linebacker -- the quarterback of their defense -- was retained. Williams, meanwhile, will only bolster a fearsome front that already included and . I'm a backer, and I think he can make good on the flashes of promise we've seen, especially under new coordinator Chan Gailey, who will iron out the erratic throws and forced pa ses and help Smith establish consistency. Receivers and , running backs and and guard will further boost the offense and improve Geno's chances of breaking out. And if the young quarterback falters, New York can turn to veteran backup , whom Gailey knows well from their days together in Buffalo.New head man Todd Bowles is an exceptional coach, and new general manager Mike Maccagnan has done a heck of a job, especially in the draft. Much depends on the quarterback play, but if Smith makes a leap, the can definitely contend for a wild-card spot.2) Miami DolphinsKey additions: DT , TE , WR .Suh might have , but it's hard to overstate the impact he can have on a team. He's a tremendously competitive and hard-working guy who makes everyone around him better, and he should seriously elevate a defense that was already decent () before he arrived.Health has been an i sue for Cameron, but if the tight end can stay on the field, he'll be a boon to quarterback . Cameron's larger, faster and more athletic than departed tight end . Parker and second-year pro are two very good young receivers, while trade acquisition Kenny Still also should help. (UPDATE: Ian Rapoport reports that . He is expected to be ready for the season opener.) Getting back tackle -- who mi sed seven games in 2014 -- will be huge. I think there's a great chance either the or the join the as AFC East teams in the playoffs. I like the ' overall roster a bit better, but the do have Tannehill under center and could snag a wild-card berth if the stumble.3) Philadelphia EaglesKey additions: QB , LB , RB . was a bold move, one that can pay off brilliantly, provided the oft-injured former No. 1 overall pick . In terms of ability, I like everything about Bradford; he's athletic, smart and accurate. Even accounting for the risk he'll mi s significant time, I would have made this trade if I were in Chip Kelly's shoes Deandre Carter Jersey , because the potential upside is so high -- and because the quarterbacks behind Bradford (, ) can be effective enough in this offense, should they have to play.Some thought the was somewhat lopsided in favor of the , but I like Alonso quite a bit. The playmaking linebacker had 159 tackles and four picks as a rookie in 2013 before mi sing the 2014 season with a torn ACL. He's a tough-minded competitor who makes your defense better, and I think he'll have a significant impact playing for his old Oregon coach. Veteran cornerbacks and and second-round pick will boost a pa s defense that in 2014.Losing McCoy and receiver could hurt, but I really like rookie receiver ; the first-round pick has a chance to be special, like was with the last year. Murray might not approach his league-leading yardage total from last season, but Philly's system suits him. Between Murray, free agent and incumbent , the are set at running back.Kelly's a pretty smart guy. In Year 3 of his tenure, opposing teams are bound to have adjusted to his scheme somewhat, which no doubt motivated Kelly to adjust his roster to better match his approach.4) Houston TexansKey additions: QB , WR , DT .Bill O'Brien's squad -- which won nine games with three starting quarterbacks in 2014 -- has talent. Signing Hoyer, who I expect to beat out for the top job, will go a long way toward stabilizing the position and should help Houston reach double digits in wins this season. O'Brien coached Hoyer in New England and knows how to get the most out of him, especially with a promising rookie (Strong) joining rising youngster on the receiving corps. Re-signing , one of Darrynton Evans Jersey the more underrated right tackles in the NFL, was key, as Newton is a good run-blocker and pa s protector. Wilfork might be entering his 12th NFL season, but I think he played pretty good, all things considered, last year; I wouldn't say he's over the hill just yet. Safety will also help this -led defense. First-round pick (cornerback) and second-round pick (linebacker) are both capable of starting; Johnson, who can cover and play the run, has potential, while McKinney brings size and competitivene s. I also like sixth-round pick (linebacker), who should be a great addition to the special teams unit. Getting 16 effective games out of , who lost 12 games to injury in 2014 and underwent knee surgery in December, will be key.O'Brien is a Kiran Amegadjie Jersey heck of a coach with a history of shepherding quarterbacks to succe s, and I expect Houston to compete for a playoff spot.5) Indianapolis ColtsKey additions: RB , WR , DE .I can't say enough good things about , but the really needed to addre s the running game. Gore is a tough, hard-nosed guy who will block, runs well and can catch the ball when needed. I'm not sure he'll reach the 1,000-yard mark, but I'm not sure he'll need to; 750 or so should be enough, considering the reached the AFC title game without a single back topping 520 last season. Johnson isn't the big-play threat he once was, but the veteran wideout can still make the clutch reception when you need a first down. He'll also help keep defenses from keying on . Plus, he'll likely be on something of a crusade after .The boosted their pa s rush by signing Cole (85.5 career sacks) and shored up the defensive line with . And while they didn't use their first-round pick on defense, they did help the unit in the draft; I like third-rounder , a cover corner who can play in the slot, and fellow third-rounder , a big defensive lineman with pa s-rushing skills. Presuming the had receiver rated well above the defensive players available at the time, I can't fault them for prioritizing talent over need with the 29th overall pick. 6) St. Louis RamsKey additions: RB , QB , OTs and .Jeff Fisher wants to run. He hasn't had a 1,000-yard back in St. Louis since put up 1,045 in 2012, and none of his squads have finished better than 19th in rushing, but I think he's finally found a back to build around in Gurley. The also drafted three offensive linemen (Havenstein, Brown and ), two of whom (Havenstein and Brown) have a chance to start. Between the fresh blood and what I expect will be the continued improvement of last year's second overall pick, tackle , St. Louis' ground game should be in good shape.I liked the decision to ship Bradford to Philly in exchange for Foles. (Yes, I thought the trade was win-win for both sides.) Foles might not have the star power or upside of Bradford. But while Foles has had his share of injury i sues, I think he's more reliable, at this point, than Bradford, who hasn't played in a regular-season game since Oct. 20, 2013. The can count on the big-armed Foles to be there and give them significantly more than they got from backups and last season.I loved the signings of defenders (tackle) and (linebacker). Fairley has plenty to prove and will benefit from being part of a rotation in St. Louis. Ayers can rush the pa ser or drop into coverage, and he brings a solid veteran presence, despite his relative youth (25). The Mario Edwards Jr. Jersey have a good roster and a chance to make some noise, as long as the off-field subplot of a potential move to Los Angeles doesn't distract the players too much.OTHER TEAMS I CONSIDERED: : New running back was a big get. : Defense should be helped by first-round pick . : Keeping and was crucial. : Second-round pick is a heck of a player. : Any offseason in which you land a dynamic weapon like is a good offseason.Follow Gil Brandt on Twitter __.
