Here's a look at the top 5 players at each position as free agency gets underway ...
Top Five Middle Linebackers
The heart and soul of the Ravens could be on the way out of town. Lewis is a fierce player and leader. He is still one of the best hitters in the game and remains a solid playmaker.
Peterson fell out of favor with coach Jack Del Rio this year and was limited to 10 starts. He isn't the playmaker he was a couple of years ago, but Peterson can be a solid starter.
Put up good numbers in his first season starting for the Saints. Only 26 years old. Should be a good starter in the middle for several more years.
Big, thick linebacker that is built to stuff the run. Might not have the speed and range to play in a 4-3. Solid player in the Browns 3-4. Finished second on the team in tackles and also had six tackles-for-loss.
Veteran linebacker is another one of those guys who just gets the job done. Led the Jets with 119 tackles in 2008.
