AFC SOUTH
Jacksonville Jaguars
Offseason grade: B+
First-round pick Dante Fowler Jr. and veteran tight end Julius Thomas were the big-ticket personnel additions for Jacksonville last season. Both got hurt. Neither factored as anticipated, which means Bill Polian's comments from last offseason might still apply: "They are in a situation where everything goes wrong all the time, but they are working hard enough that their luck will change." Bringing back former quarterbacks coach Greg Olson as offensive coordinator and adding to the offensive personnel panned out. The Jaguars jumped from 32nd to 14th in points scored and from 31st to 21st in offensive expected points added per game. If only they could have realized similar gains on the defensive side of the ball.

Houston Texans
Offseason grade: C+
The Texans re-signed Ryan Mallett, added Brian Hoyer and parted with Ryan Fitzpatrick. It wasn't much of a solution at quarterback, but then again, what were the options? Getting a second crack at the 2014 quarterback draft class was not one of them, so the Texans spun their wheels and probably lost some ground at the position. The moves they made in the secondary paid off. First-round choice Kevin Johnson joined the re-signed Johnathan Joseph and Kareem Jackson to give Houston a good combination of talent and depth. Getting a career-high 12 sacks from the newly re-signed Whitney Mercilus was another plus for Houston.

Indianapolis Colts
Offseason grade: C+
The Colts made a series of boom-or-bust moves that went bust. They still nearly won the AFC South, but they finally paid the price for failing to build an effective offensive line and scheme to protect quarterback Andrew Luck. With Luck struggling before finally leaving the lineup with a multitude of injuries, the Colts failed to maximize veteran offseason additions Frank Gore and Andre Johnson. They also had a hard time getting value from first-round receiver Phillip Dorsett, who missed five games entirely and played more than 35 percent of the snaps just once all season -- in Week 17.
Re-grade: D-
Tennessee Titans
Offseason grade: B-
First-round pick Marcus Mariota finished his first season with the fifth-highest QBR (61.0) among 29 qualifying rookies over the past decade. That was a notch better than Jameis Winston, Teddy Bridgewater and Cam Newton as first-year players -- and just behind Andrew Luck. The addition of Mariota salvages an offseason marked by decent but not highly impactful moves. Brian Orakpo was about what the Titans expected, particularly before Derrick Morgan's injury (re-signing Morgan was another plus from the offseason). Free-agent addition Perrish Cox signed for too much money. Watching Michael Oher fare better elsewhere after leaving Tennessee had to hurt.
Re-grade: B-
AFC WEST
Denver Broncos
Offseason grade: C
The middling grade for Denver reflected a feeling that the team failed to upgrade its offensive line sufficiently after reducing Peyton Manning's salary. On-field results justified those concerns. A season-ending injury to left tackle Ryan Clady was both unfortunate and not entirely surprising given that he missed 14 games in 2013. The Broncos did not get much from their draft class, which came as little surprise. Denver weathered these deficiencies and Manning's sharp decline to reach the Super Bowl thanks in part to the addition of Wade Phillips as defensive coordinator. That move must go down as one of the best a team made this past offseason. It's why the Broncos' offseason mark is higher now.
Re-grade: B-
Kansas City Chiefs
Offseason grade: B
Adding receiver Jeremy Maclin through free agency and cornerback Marcus Peters through the draft armed Kansas City with a key playmaker on each side of the ball. Both played prominent roles in Kansas City reaching the postseason. Second-round choice Mitch Morse also became a valued contributor on the offensive line. The Chiefs were able to re-sign both Justin Houston (long term) and Tamba Hali (short term), while committing to versatile defensive back Ron Parker. Those moves helped Kansas City win with its defense for much of the season.
Re-grade: B+
Oakland Raiders
Offseason grade: B-
Adding Amari Cooper, Mario Edwards Jr. and Clive Walford through the draft paid immediate dividends, as did re-signing safety Charles Woodson. The Raiders also got good value on the veteran market by signing receiver Michael Crabtree to a deal worth $3.2 million annually. Oakland got about what it expected from pricier free-agent additions in center Rodney Hudson and two-down defensive tackle Dan Williams. Aldon Smith was a miss, but the cost was minuscule. Improving from 3-13 in 2014 to 7-9 in Jack Del Rio's first season reflected well on his hiring as the team's sixth head coach in the past decade.
Re-grade: B+
San Diego Chargers
Offseason grade: B-
Linebacker Denzel Perryman provided immediate positive impact as a second-round pick. Veteran cornerback Patrick Robinson was a success story on a contract averaging $2 million per year. Tackle Joe Barksdale was also a good value on a one-year deal. Those were notable successes, but the Chargers didn't get great value from their pricier free-agent additions. Orlando Franklin, Stevie Johnson and Donald Brown underwhelmed. Cornerback Brandon Flowersstruggled after re-signing for $9.1 million per year. Philip Rivers' contract situation was resolved, but the Eric Weddle situation remained uncomfortable. The Chargers also got little from first-round pick Melvin Gordon, who had fumbling issues and struggled behind a poor line. Is he the answer?
