The NFL.com fantasy crew tracks some of the key free agent movement and how it will affect fantasy values heading into 2013.

Matt Hasselbeck doesn’t have a ton of fantasy value, but he sure helps the stock of the players around him in Tennessee.

A number of teams will use the NFL Scouting Combine not only as a way to look at new players, but hopefully hammer out some contract details with potential free agents.

Devin Hester and Matthew Stafford were among the notable players who sustained injuries in Week 13.

Bo Scaife, the Titans’ leading receiver last season, will be sidelined in Week 2, the result of a knee injury suffered on what the tight end described as a “cheap shot” from Steelers LB Jerome Harrison in Week 1. Scaife caught five passes for 48 yards in that game.

Steelers LB Lawrence Timmons didn’t practice for the third consecutive day because of an ankle injury and is listed as doubtful to play in Thursday night’s season opener against the Titans.

One of the biggest surprises in the NFL last season was the Titans’ improbable run to a league-best 13-3 regular-season record and the dethroning of the almighty Colts, snapping Indianapolis’ five-year reign as AFC South champions. Even more stunning was the rebirth of 36-year-old Kerry Collins, who led the Titans to a 10-0 start and a No.1 seed in the AFC playoff race. Now, everyone wants to know if the Titans can do it again with Collins at quarterback.
