Bills OLB Mario Williams recorded just two sacks in the final eight games of the season.
Williams posted 13 sacks on the season, and got off to a very hot start with multi-sack days in three of the Bills' first seven games, including 4.5 against the Panthers in Week 2. He cooled significantly in the second half of the season, all but disappearing for stretches. We expect Williams to remain a boom-bust DL1 in IDP leagues for 2014.
USA Today's Tom Pelissero has heard free agent TE Dustin Keller (knee) is "on track to return."

Keller was having a huge camp in 2013 with the Dolphins before tearing his ACL, MCL, and PCL, dislocating his right knee in Miami's third preseason game. There's no telling what Keller has left -- the injury was gruesome and he's entering his age-30 season -- but it's good news for him. NFL teams would probably want to see Keller work out before entertaining signing him.
Lions extended an exclusive rights free agent tender to WR Kris Durham.

He's now owed $570,000. Durham, 26, appeared in all 16 games in 2013, starting 13 and catching 38 passes for 490 yards with two touchdowns. This was never by design, of course, as Durham was forced onto the first team by injury. He registered a whopping ten dropped passes and ranked among the worst wideouts in the NFL in "catch rate." Durham is best suited as a No. 4 or 5 receiver.
