Forget about March Madness as the NFL has already staked it’s claim to this month with a frenzied start to free agency. Players are moving from team to team quicker than green beer will flow on St. Patty’s day. A week into free agency and it feels like we may have a minute to catch our breath before the wave of second-tier signings kick into high gear. Here is a quick-hitting look at some of the IDP signings so far that will most affect the fantasy football landscape in 2015. No, I am not addressing every single signing to date because not every single signing merits analysis. For the most part, if you don’t see a name covered here it means I don’t see his value going up or down enough on his new team to warrant addressing. Some of that may change as schemes and positions become solidified but as of now these are the signings that make me some…hmmmm. Ndamukong Suh, DT, MIAMI: The Dolphins landed the biggest fish in free agency (see what I did there) even if took a little extra time to get finalized. Suh remains an elite DT option for fantasy purposes and immediately raises the stock of both Cameron Wake and Olivier Vernon. Kiko Alonso, ILB, PHILADELPHIA: As long as the knee checks out, the kid will definitely improve the Eagles defense. The presence of DeMeco Ryans could eat into his tackle totals so I'm not convinced that his fantasy stock goes up at all. Curtis Lofton, ILB, OAKLAND: Lofton may not be an upper echelon (or even middle echelon for that matter) NFL linebacker but he consistently puts up triple-digit tackle numbers. Yeah, we like that for fantasy purposes on a defense that figures to be on the filed a lot. Tramon Williams, CB, CLEVELAND: Williams should get tested a lot playing opposite Joe Haden and that should translate into some decent fantasy production. He has posted three or more interceptions in six of his last seven seasons. Sean Weatherspoon, ILB, ARIZONA: Don’t sleep on ‘Spoon’ this season as he figures to slot into Larry Foote’s role. Foote put up 84 total tackles last season and is 137 years old. Brandon Browner, CB, NEW ORLEANS: Unless your league awards points for penalties or suspensions, Browner is best left alone on fantasy draft day. He had six interceptions back in 2011 and has totaled five in the three seasons since. Justin Durant, LB, ATLANTA: Another sneaky good name to keep close by on draft day. When he’s been a three-down player Durant has been fantasy relevant. He is in line for a three-down role for the Falcons. Terrance Knighton, DT, WASHINGTON: He’s a big guy with a big name in NFL circles. The Washington defense will be better with him but fantasy rosters are better without him. No value in all but very deep DT required leagues. Very, very deep. Adrian Clayborn, DE, ATLANTA: Injuries have derailed what was once a promising future for Clayborn. The Falcons are desperate for pass rushing options so they are hoping Clayborn has a bounce back 2015. Hope is not a strategy for fantasy owners. Pass. Antrel Rolle, S, CHICAGO: Will solidify the Bears secondary and has posted 70-or-more total stops in eight of the last nine seasons. Has also accounted for 17 turnovers (13 interceptions and 4 forced fumbles) in the past four seasons. Jabaal Sheard, OLB, NEW ENGLAND: The Pats resurrected the career of Akeem Ayers so Sheard could be a nice late round IDP selection in big play scoring formats. Only take him if he falls to a position of value in your draft. Dannell Ellerbe, ILB, NEW ORLEANS: As long as the hip injury that cost him most of last season is fully healed, Ellerbe could hold some value in 2015. The Saints need help at LB and Ellerbe could snag a three-down role making him a possible low end LB 2 producer. Tyvon Branch, S, KANSAS CITY: It is all about staying healthy for Branch if he’s to help fill the void left by Eric Berry’s illness. From 2009-2012 he averaged 107 total tackles per season. In the last two seasons he’s played a total of five games. Haloti Ngata, DT, DETROIT: A Band-Aid to help patch the holes left by Suh and Fairley’s departure. Will hold value in DT required formats but little to none in standard scoring leagues. Bruce Carter, ILB, TAMPA BAY: Takes his tour of inconsistency to the Buccaneers and will likely man the strong side. I am done gambling on what Carter will provide my IDP squads and suggest folks follow my lead. J.T. Thomas, ILB, NEW YORK GIANTS: After bouncing from a few teams, Thomas flashed fantasy usefulness last season in Jacksonville after Posluszny went down. He will have the chance to earn a three-down role in a depleted Giants linebacking corps. Pernell McPhee, OLB, CHICAGO: Had 7 ½ sacks while playing a rotational role for Baltimore last season (540 snaps). Will flourish in what should be a 3-4 scheme for the Bears and the chance to be a three-down player. Brian Orakpo, OLB, TENNESSEE: Lack of tackle production will continue to limit Orakpo’s upside. Will hold more value in big play scoring formats. Will help the Titans more than he will fantasy owners. Rahim Moore, S, HOUSTON: This signing should actually help D.J. Swearinger’s value more than it does Moore’s. Look for Swearinger to play down in the box a lot more next season racking up tackle numbers. Trent Cole, OLB, INDIANAPOLIS: I like Cole a lot more if Robert Mathis is healthy as the bookend option across from him. Either way, he is a better option than the underachieving Bjoern Werner and overpaid Erik Walden. Da’Norris Searcy, SS, TENNESSEE: Searcy will finally get to play an every down role in the position vacated by the departed Bernard Pollard. This could be a breakout season playing the very fantasy favorable SS position in Tennessee. Nick Fairley, DT, ST. LOUIS: There are a lot of mouths to feed along the Rams defensive line for fantasy purposes. Fairley hasn’t proven he can stay healthy and even if he does, he will be a rotational player. This is a quick look at the first wave of signings that I feel most effect the IDP landscape. There will be plenty more moves to examine (I’m guessing players are moving as I type this) and they will be broken down in future articles.
