(Harry How/GettyImages) NFL free agency begins March 10.

With the deadline to apply the franchise tag expired, we now know that some big free agents are going to hit the open market. Ndamukong Suh, DeMarco Murray, and Julius Thomas are all going to be free agents.

The salary cap has been set to $143.3 million, a 7.5% increase from 2014. As a result, a decent number of teams will have some serious money to spend.

Eleven teams (more than one-third of the league) are at least $30 million below the cap. Four teams are at least $50 million below the cap.

On the other end of the spectrum, the Saints are in salary-cap hell, and the Patriots are going to have to get creative to improve their roster.

Here is the ranking of all 32 teams by cap room (via OverTheCap.com):

1. Jacksonville Jaguars — $68.5 million

2. Oakland Raiders — $54.8 million

3. Cleveland Browns — $53.1 million

4. New York Jets — $50.0 million

5. Indianapolis Colts — $43.9 million

6. Tennessee Titans — $43.8 million

7. Cincinnati Bengals — $39.4 million

8. Tampa Bay Buccaneers — $33.4 million

9. Atlanta Falcons — $32.6 million

10. Green Bay Packers — $32.5 million

11. Buffalo Bills — $30.4 million

12. San Diego Chargers — $29.4 million

13. Chicago Bears — $28.8 million

14. Washington Redskins — $27.4 million

15. Philadelphia Eagles — $26.2 million

16. Seattle Seahawks — $24.4 million

17. Minnesota Vikings — $19.9 million

18. Detroit Lions — $18.7 million

19. Carolina Panthers — $16.0 million

20. Denver Broncos — $15.5 million

21. Arizona Cardinals — $13.5 million

22. New York Giants — $12.7 million

23. Houston Texans — $12.6 million

24. Miami Dolphins — $9.5 million

25. Pittsburgh Steelers — $7.3 million

26. St. Louis Rams — $6.9 million

27. Dallas Cowboys — $6.6 million

28. San Francisco 49ers — $6.5 million

29. Baltimore Ravens — $4.1 million

30. Kansas City Chiefs — ($5.7 million above cap)

31. New England Patriots — ($12.3 million above cap)

32. New Orleans Saints — ($22.4 million above cap)

Keep in mind that these numbers are before teams re-sign their own players and give guys under small contracts lucrative extensions. The Seahawks, for example, are going to be cap-strapped because they have to give Russell Wilson a raise that could add up to $19 million to their cap.

Here are the 10 best free agents available, according to NFL.com:

1. Ndamukong Suh, defensive tackle

2. Devin McCourty, safety

3. Julius Thomas, tight end
