But we saved the best for last as we take a look at what could be a deep free-agent pool at the linebacker position come March 9.

Be it inside or outside, the 3-4 or the 4-3, we are taking a look at the top 12 linebackers who may be or already are available for hire (listed in alphabetical order).

From pass-rushers to tackling machines to those with some good, old versatility, it’s a deep enough group that includes David Hawthorne (New Orleans Saints), Sean Weatherspoon (Arizona Cardinals), Chad Greenway (Minnesota Vikings) and Calvin Pace (New York Jets). You can check out the complete list here, courtesy of Spotrac.

There could be a flurry of activity over the next few weeks for all 32 NFL teams when it comes to this deep, vital group of defenders.
