Insider free agency preview:

Top 50 free agents | Best fits for top FAs | Riskiest FAs | Best values | Five teams for Mario Williams | Six teams in danger in FA

With free agency beginning at 4 p.m. on Tuesday, it seemed appropriate to rank the top 50 unrestricted free agents this year.

There are some elite free agents out there, including potential franchise-altering quarterbacks Peyton Manning and Matt Flynn, both of whom are probably ranked lower than you think. Even though several wideouts were franchised, there is still talent available at WR, with eight players appearing on the list. The defensive tackle position also has eight players, while there are six linebackers and six defensive tackles.

Remember, while this list factors in age, upside and other factors, it's primarily based on each free agent's value right now.
