Free agency in the NFL begins on March 13 and leading up to that date I’ll go position by position while highlighting the best players, best bargains, as well as the riskiest investments.

Best in Class: Take your pick.
This is the deepest pool of free agent receivers that I’ve seen in a long time. Wes Welker, Mike Wallace, Vincent Jackson, Dwayne Bowe, Marques Colston, Brandon Lloyd, Stevie Johnson, DeSean Jackson, Reggie Wayne and Robert Meachem comprise the top 10 free agents, but Mario Manningham, Laurent Robinson and Harry Douglas could also be available next month. Welker seems like a perfect fit for the Patriots’ offense and will likely stay in New England, but Wallace could be available if the Steelers can’t figure out a way to fit him under their cap. When healthy and not in the midst of a contract holdout, V-Jax is one of the more versatile receivers in the league in that he’s a vertical threat with soft hands who can also block in the running game. Bowe, Colston, Lloyd, Johnson, Jackson and Wayne have been, or still are No. 1 options in the passing game and Meachem certainly has the talent to be a No. 1 given his skill set. Teams needing a receiver have no excuse not to address that hole this offseason.

The Biggest Risk: DeSean Jackson
Jackson is only 25 and is drenched in big play ability. But he has 35 drops over the last four seasons, was a ghost at times last year because he was seemingly worried about his contract situation, and sometimes costs his team on the field with his immaturity. Because of his big play ability and success as a punt returner, plenty of teams will be interested in Jackson’s services next month. But with so many other free agent receivers available, teams weary of his inconsistency and maturity issues can cross his name off the list if they want to. His agent must pull his hair out thinking about how much money Jackson has cost himself over the past year.

The Best Value: Brandon Lloyd
Lloyd is still going to be paid like a low-end No. 1 but at 31 he’ll be cheaper than guys like Welker, Jackson, Bowe, Wallace and Colston. He didn’t post the same numbers in 2011 as he did in 2010 but don’t forget that the quarterback situation in Denver was brutal and Sam Bradford couldn’t stay healthy in St. Louis (the team Lloyd was traded to midseason). Even at 31, Lloyd is an explosive downfield threat who also has a large catch radius. The Rams would be wise to keep him in St. Louis but if he were to hit the open market, he could turn out to be a real value for his eventual production.

Best Cost-Effective Bargain: Robert Meachem
Meachem doesn’t have the numbers or name power as other receivers that could become available next month but at 27 his ceiling is still somewhat high. He’s consistent, as he’s averaged a touchdown every 10 receptions in the regular season and has just 11 drops over the last four years. He may never develop into a No. 1 but he’s worth a shot for a team like Jacksonville that is thin at receiver and has other holes to address this offseason (and thus, might not want to spend big at one position). Meachem could wind up being a cost-effective alternative to Jackson, Bowe, Colston and the other big-name receivers in this free agent pool.
