Cliff Avril, Mike Wallace and Steven Jackson are a few of the most coveted free agents in 2013, and they'll be in high demand when the NFL's free-agency signing period officially begins on Tuesday, March 12, at 4 p.m. ET.
Signing free agents is stressful for NFL general managers. The moves these men will make in March could either push their respective teams over the hump to become contenders or sink them into salary-cap purgatory.
For the players and their agents, it's a chance to cash in on past success and potentially move on from mediocre teams to play for contenders.
These upcoming players represent the best of the 2013 NFL free-agent class.
