Here's a look at the top 5 players at each position as free agency gets underway ...
Top Five Fullbacks
All-purpose fullback, but not a great lead blocker. Teams who like to get the ball to the fullback will value his ability.
Veteran fullback has plowed over a lot of linebackers in his career. He will turn 38 in 2009, but remains a very good lead blocker.
Solid blocker with some tread left on the tire.
Former great blocker has worn down, but can still be effective with limited snaps.
Griffith is somewhat of a tweener type of fullback. He's a solid blocker and receiver. Lacks ideal size.
