The NFL draft presents the ultimate opportunity for teams to improve, but few actually do.

Over three days this week, all 32 teams will select players they feel good about and are excited to have on their team, but it usually takes a few years to see if the picks actually work out. This is our fifth annual examination of how teams have done in the past five drafts (2014-18) to see who is acing the draft and who is spinning their wheels.

The rankings are based on: how many games the draft pick has played, Pro Bowl appearances, first-team All-Pro selections and awards like MVP and Rookie of the Year. We also factored in how much the team has won during the five years, because players on losing teams tend to have an easier path to playing time.

Here are the rankings from best to worst, with last year’s ranking in parentheses:

1. Chiefs (2)

Pro Bowlers: 5

Best Pick: Patrick Mahomes (2017, first round)

Worst Pick: Phillip Gaines (2014, second)

The only team that has drafted an MVP in the past five years gets the crown this year. Patrick Mahomes, Tyreek Hill, Kareem Hunt and Marcus Peters were all great draft picks. They have not all worked out in Kansas City, but you can’t argue with the picks.

2. Cowboys (1)

Pro Bowlers: 6

Best Pick: Zack Martin (2014, first)

Worst Pick: Randy Gregory (2015, second)

Jerry Jones has built a strong team through the draft. The 2016 draft was huge, with Dak Prescott and Ezekiel Elliott. It looks like they added another strong piece in 2018 with Leighton Vander Esch, who made the Pro Bowl as a rookie.

3. Rams (4)

Pro Bowlers: 4

Best Pick: Aaron Donald (2014, first)

Worst Pick: Greg Robinson (2014, first)

Back-to-back picks of Aaron Donald and Todd Gurley in the first rounds in 2014 and ’15 gave the Rams building blocks on each side of the ball. Jared Goff looks like a keeper, and this year’s Super Bowl appearance came on the backs of many of these draft picks.

4. Bears (19)

Pro Bowlers: 7

Best Pick: Tarik Cohen (2017, fourth)

Worst Pick: Kevin White (2015, first)

General manager Ryan Pace made the trade of the year last season for Khalil Mack, but his work in the draft really helped build last year’s division champion. Cohen, Eddie Jackson and Mitch Trubisky, all taken in 2017, look like long-term stars for the team.

5. Raiders (5)

Pro Bowlers: 3

Best Pick: Khalil Mack (2014, first)

Worst Pick: Mario Edwards (2015, second)

Poor Reggie McKenzie. He did a good job rebuilding the Raiders’ roster — landing Mack, Derek Carr and Amari Cooper between 2014 and 2015. Now, Jon Gruden is undoing everything the former GM built. Mack is one of the best picks of the past five years.

6. Jaguars (10)

Pro Bowlers: 4

Best Pick: Jalen Ramsey (2016, first)

Worst Pick: Blake Bortles (2014, first)

The Bortles era in Jacksonville has finally come to a close. He showed some promise but never justified being taken third overall in 2014. Jacksonville has landed some key defensive pieces in the draft like Ramsey, Telvin Smith, Myles Jack and Yannick Ngakoue.

7. Falcons (6)

Pro Bowlers: 6

Best Pick: Vic Beasley (2015, first)

Worst Pick: Jalen Collins (2015, second)

Atlanta drafted Pro Bowl players in the 2014, ’15 and ’16 drafts. They have not landed any superstars, but have built a strong core around Matt Ryan and Julio Jones, who they drafted earlier.

8. Giants (11)

Pro Bowlers: 3

Best Pick: Odell Beckham Jr. (2014, first)

Worst Pick: Ereck Flowers (2015, first)

Giants fans may think this is way too high for Big Blue, but consider this: Just three teams have drafted two players who won Rookie of the Year in the past five years, and the Giants are one of them. They are tied for the fewest picks over this time period with 31.

9. Titans (14)

Pro Bowlers: 2

Best Pick: Kevin Byard (2016, third)

Worst Pick: Bishop Sankey (2014, second)

Byard and Jack Conklin have both been first-team All-Pro. Taylor Lewan is another part of their foundation they found in the draft. The jury is still out on quarterback Marcus Mariota, and his development is the key to evaluating this period of Tennessee drafts.

10. Browns (27)

Pro Bowlers: 4

Best Pick: Joe Schobert (2016, fourth)

Worst Pick: Johnny Manziel (2014, first)

One of the worst drafting teams is becoming one of the best, and that is showing in an improved roster. Myles Garrett, Baker Mayfield and Denzel Ward all look like possible stars in Cleveland.

11. Saints (28)

Pro Bowlers: 4

Best Pick: Alvin Kamara (2017, third)

Worst Pick: Stanley Jean-Baptiste (2014, second)

Another team that had some bad drafts in the past decade but has turned it around lately. The 2017 draft class, led by Kamara and Marshon Lattimore, is one of the best of the past five years.

12. Vikings (3)

Pro Bowlers: 4

Best Pick: Anthony Barr (2014, first)

Worst Pick: Laquon Treadwell (2016, first)

Minnesota built a strong roster through the draft in the early part of this decade, but they have started to slip. The window is closing on their current group of players.

13. Ravens (13)

Pro Bowlers: 1

Best Pick: C.J. Mosley (2014, first)

Worst Pick: Breshad Perriman (2015, first)

The Ravens’ drafts have been about quantity, not necessarily quality. They have drafted just one Pro Bowl player in the past five years — Mosley. But their 48 picks are third in the NFL over that time, and they have drafted plenty of starters.

14. Dolphins (17)

Pro Bowlers: 3

Best Pick: Jarvis Landry (2014, second)

Worst Pick: Charles Harris (2017, first)

The Dolphins have taken some good players, but they have not lasted in Miami for various reasons. Landry and Jay Ajayi are two of the three Pro Bowl players they have drafted and both no longer play in South Florida.

15. Steelers (9)

Pro Bowlers: 4

Best Pick: Ryan Shazier (2014, first)

Worst Pick: Senquez Golson (2015, second)

The key for the Steelers to survive their recent drama will be the development of some recent draft picks. The 2017 class featured JuJu Smith-Schuster and James Conner, who the Steelers are counting on to become stars.

16. Texans (16)

Pro Bowlers: 3

Best Pick: Jadeveon Clowney (2014, first)

Worst Pick: Kevin Johnson (2015, first)

Houston made the big move in the 2017 draft to land Deshaun Watson. So far, that move looks strong. Their future depends on his development and building around him.

17. Seahawks (21)

Pro Bowlers: 2

Best Pick: Tyler Lockett (2015, third)

Worst Pick: Malik McDowell (2017, second)

Seattle built its Super Bowl team through the draft, but have dropped off since then. Part of the problem has been no first-round picks in 2014, ’15 or ’17.

18. Packers (8)

Pro Bowlers: 2

Best Pick: Davante Adams (2014, second)

Worst Pick: Jason Spriggs (2016, second)

Part of the drama around Aaron Rodgers and former coach Mike McCarthy was caused by a lack of talent around Rodgers. Green Bay is wasting its quarterback’s prime.

19. Chargers (12)

Pro Bowlers: 4

Best Pick: Joey Bosa (2016, first)

Worst Pick: Jeremiah Attaochu (2014, second)

The Chargers have landed some top-tier players with Bosa, Melvin Gordon and Derwin James, but they don’t have much depth. They have had 33 picks in the past five years — just two teams have had fewer.

20. Buccaneers (24)

Pro Bowlers: 3

Best Pick: Mike Evans (2014, first)

Worst Pick: Roberto Aguayo (2016, second)

Bruce Arians takes over a roster that does not have many stars on it. Jameis Winston, taken No. 1 overall in 2015, remains a question mark.

21. 49ers (26)

Pro Bowlers: 2

Best Pick: George Kittle (2017, fifth)

Worst Pick: Reuben Foster (2017, first)

No team has had more draft picks in the past five years than the 49ers with 52. They don’t have great results to show for those numbers. They have drafted two Pro Bowl players and no first-team All-Pro players.

22. Colts (32)

Pro Bowlers: 1

Best Pick: Darius Leonard (2018, second)

Worst Pick: Phillip Dorsett (2015, first)

Indianapolis has been one of the worst drafting teams in football until last year. Chris Ballard won the 2018 draft with Quenton Nelson and Leonard both looking like long-term studs for his team.

23. Panthers (20)

Pro Bowlers: 1

Best Pick: Trai Turner (2014, third)

Worst Pick: Kony Ealy (2014, second)

Carolina is tied for the fewest picks, 31, in the past five years. The Panthers have not done much with those picks. A roster that was good enough to win the NFC in 2015 has slowly deteriorated with some bad drafts.

24. Cardinals (7)

Pro Bowlers: 1

Best Pick: David Johnson (2015, third)

Worst Pick: Troy Niklas (2014, second)

Just two teams have had fewer picks than the Cardinals in the past five years. Arizona drafted well early in the decade, but it has dropped off lately, which is why the Cardinals will be drafting No. 1 this year.

25. Lions (18)

Pro Bowlers: 1

Best Pick: Eric Ebron (2014, first)

Worst Pick: Ameer Abdullah (2015, second)

Here is how bad it has been for the Lions: Ebron is the only player they have drafted in the past five years to make the Pro Bowl, but he did it with the Colts last year.

26. Redskins (22)

Pro Bowlers: 1

Best Pick: Brandon Scherff (2015, first)

Worst Pick: Su’a Cravens (2016, second)

Daniel Snyder’s team has not been able to figure things out in the draft for a while now. They have tried to steal from Nick Saban’s success by draft five players from Alabama over this time, but it has not worked.

27. Jets (23)

Pro Bowlers: 2

Best Pick: Jamal Adams (2017, first)

Worst Pick: Christian Hackenberg (2016, second)

The 12-person 2014 draft class (taken by former GM John Idzik) only has one player remaining on the team. Current GM Mike Maccagnan has to hope Sam Darnold becomes a start to improve his drafting record.

28. Eagles (15)

Pro Bowlers: 1

Best Pick: Carson Wentz (2016, first)

Worst Pick: Marcus Smith (2014, first)

Everything hinges on how Wentz develops for this team. Injuries have slowed his progress, but he looks like he will be a star. The Chip Kelly era still drags the overall draft grade down.

29. Bengals (25)

Pro Bowlers: 0

Best Pick: Tyler Boyd (2016, second)

Worst Pick: Cedric Ogbuehi (2015, first)

It is never a good sign when there are trade rumors about your first-round pick from two years ago like there are with John Ross. New coach Zac Taylor is going to need to find some players.

30. Broncos (30)

Pro Bowlers: 0

Best Pick: Matt Paradis (2014, sixth)

Worst Pick: Paxton Lynch (2016, first)

John Elway had the golden touch when he began as GM, and it helped Denver win Super Bowl 50. But he has struggled lately, and the Broncos have little to show from recent drafts.

31. Patriots (29)

Pro Bowlers: 0

Best Pick: James White (2014, fourth)

Worst Pick: Dominique Easley (2014, first)

The Patriots have proven you don’t need to draft well to win Super Bowls. Just make sure you have Bill Belichick and Tom Brady, and you’ll be fine. In their defense, the Patriots’ success has led to them drafting late. Their average first pick has been 45.2, the lowest in the NFL.

32. Bills (31)

Pro Bowlers: 0

Best Pick: TreDavious White (2017, first)

Worst Pick: Sammy Watkins (2014, first)

Bills GM Brandon Beane is trying to clean up from the previous regime’s major mistakes in the draft like the big trade for Watkins in 2014.

Best pick in:

2014: Aaron Donald, Rams

2015: Todd Gurley, Rams

2016: Tyreek Hill, Chiefs

2017: Alvin Kamara, Saints

2018: Darius Leonard, Colts
