Now that the 2012 NFL regular season has concluded, those teams that didn't make the playoffs, will turn their attentions to free agency.

2013's free agent crops is particularly strong at wide receiver, offensive tackle and safety. There is also plenty of credible talent available at running back and defensive tackle.

These are the top 10 players available in this year's free agency class.

10. Randy Starks, DT, Miami Dolphins

Randy Starks has quietly developed into a dominant interior defensive lineman. The 29-year-old has become the key figure for the Miami Dolphins' new-look 4-3 defense.

Naturally powerful, Starks has the strength to occupy blockers as a 2-gap tackle. He is also quick and technically sound enough to attack single gaps and penetrate the backfield.

The 6'3", 305-pounder can anchor 3-4 and 4-3 schemes. He should receive plenty of interest.

9. Fred Davis, TE, Washington Redskins

Fred Davis was lost for the season in Week 7, but remains a dynamic, playmaking tight end. The Washington Redskins youngster is a quick and intelligent receiver across the middle.

He is versatile enough to create big gains from the line, slot, or even split wide. Davis has had disciplinary issues in the past, including a suspension for drug abuse.

However, he is a skilful pass-catcher who is worth a gamble.

8. Jairus Byrd, FS, Buffalo Bills

There are few more prolific ball hawks in the game than Jairus Byrd. The opportunistic Buffalo Bills defensive back has forced 28 turnovers in four seasons, including nine in 2012.

A true center fielder at free safety, Byrd has a knack for making game-changing plays. That's a priceless commodity in any NFL era.

7. Jake Long, OT, Miami Dolphins

It's not often that a left tackle as skilled as Jake Long hits the open market. However, a season-ending injury suffered in Week 13 and a slight loss of form, could prompt Long's exit from Miami.

The first overall pick in 2007, Long has dominated at times during his short career. Powerful and aggressive, they aren't many more reliable and capable blind side protectors than Long.

6. Dashon Goldson, FS, San Francisco 49ers

Super-smart safety Dashon Goldson should receive plenty of attention once free agency begins. He is a savvy athlete who reads the game well and breaks on the ball decisively.

Goldson is a natural focal point for a coverage scheme. He is also a punishing tackler and capable in run support.

5. Ryan Clady, OT, Denver Broncos

Ryan Clady is arguably the most technically proficient left tackle in football. He is blessed with exceptional footwork and uses his hands and frame very well.

Clady is an intelligent lineman who anticipates and quickly reacts to pass rush moves. He is also a mobile tackle who can attack the second level of a defense in the running game.

It seems unlikely the Denver Broncos would let Clady walk. But that shouldn't stop teams trying to tempt the ultra-talented 26-year-old with major offers.

4. Henry Melton, DT, Chicago Bears

Henry Melton is the cornerstone of the Chicago Bears 4-3 front and one of the best young defensive tackles in the league. He is a nimble-footed pass-rusher who causes havoc for opposing blocking schemes.

Melton is a 3-technique who specialises in splitting the guard-tackle gap. A quick penetrator, Melton is athletic enough to attack the backfield from various rush angles. He is the best 4-3 player on the market.

3. Wes Welker, WR, New England Patriots

Wes Welker can still find the gaps in zone coverage better than anybody. The diminutive, speedy veteran is the perfect outlet on third downs.

At 31, Welker's best years may be behind him, but he will still be a sought after, free agent prize.

2. Greg Jennings, WR, Green Bay Packers

Greg Jennings is the most dynamic wide receiver available in free agency. He has excellent hands, is intelligent enough to work underneath and still offers the speed to stretch defenses deep.

Jennings seemed out favour with the Green Bay Packers at the start of the season. However, he has rebounded to showcase his considerable skills in the last two games.

If he hits the open market, teams will be queuing up to grab this legitimate number one receiver.

1. Steven Jackson, RB, St. Louis Rams

Steven Jackson is easily the best running back in 2013's free-agent class. The 29-year-old is still a bruising, power runner, who has just registered his eighth-straight 1,000-yard season.

Jackson is also still a useful receiver and a thumping blocker. He is a true feature back who should have at least two more productive years left.

The stellar veteran deserves to close his exemplary career with at least one trip to the playoffs.
