If we do lose some of these guys who will replace them. Obviously some current backups will be taking over but wee can't expect that in every situation and if they do what of our depth? Just thought I would throw a few names out to get conversation started. DT Jason Jones (26, 6-5, 276, Titans): He's a good interior pass rusher who might also work outside in a 3-4 defense. G Ben Grubbs (28, 6-3, 310, Ravens): He's probably the best interior O-line option after Nicks. TE Jacob Tamme (27, 6-3, 236, Colts): He was a Dallas Clark clone while filling in for him in 2010 (67 rec., 631 yards, 4 TDs). With the spreading trend of two-tight-end offenses, Tamme could be a better option now than Clark, who's 33 and often in the trainers' room. C Scott wells (31, 6-2, 300, Packers): FA Type: Unrestricted A bit undersized and maybe a bit underappreciated, though he earned his first Pro Bowl nod in 2011.A key part of the Packers' offensive line, Wells has a good rapport with QB Aaron Rodgers and ranks as one of the top interior linemen available. The question is: Will Packers GM Ted Thompson give a multiyear deal to a lineman on the wrong side of 30? Considering Wells' value to the line, there are some who believe that would be a good move. TE John Carlson (28, 6-5, 241, Seahawks): A shoulder injury cost him last season and probably some money in the market. Still, he's got good hands and blocks well enough. Jeremy Zuttah (TB) - OG Brett Romberg (ATL) - OC Kendall Langford DE | Miami Dolphins Age: 26 | FA Type: Unrestricted Solid against the run, the 6-6, 295-pound Langford wasn't as productive in 2011 as he had been in past seasons, but he certainly could hold appeal to clubs employing 3-4 fronts. He might be on the underrated side. Mark Anderson DE | New England Patriots Age: 29 | FA Type: Unrestricted The pass-rush specialist had 10 sacks in the regular season and added 2½ more in the playoffs, with 1½ coming in Super Bowl XLVI. While Anderson isn't an every-down player, he has shown he can get after opposing QBs, which gives him value in a pass-happy league. Michael Robinson FB | Seattle Seahawks Age: 29 | FA Type: Unrestricted The one-time collegiate quarterback earned Pro Bowl honors as a blocker in 2011. He also is an exceptional special-teams player. Manny Lawson OLB | Cincinnati Bengals Age: 28 | FA Type: Unrestricted Lawson, who has starting experience in 3-4 and 4-3 fronts, notched 51 tackles and 1½ sacks for Cincinnati a season ago. He's shown some pass-rush ability in the past, most notably in 2009 with San Francisco, when he recorded 6½ sacks.
