Vikings signed CB Captain Munnerlyn to a three-year contract with a max value of $15 million.
Munnerlyn is obviously stretched outside at 5-foot-8 and 195 pounds, but he's one of the best slot corners in the game. Still only 26 -- he turns next month -- Munnerlyn turned in a breakout 2013 campaign as a 16-game starter, setting career highs in tackles (74), sacks (3.5), and pass breakups (12). He has four pick sixes over the past two seasons. Look for Munnerlyn to start outside on early downs and cover the slot in Mike Zimmer's nickel package.
Cowboys signed LB Will Herring, formerly of the Saints.
Herring, 30, is purely a special teamer who will backup at outside linebacker.
The Steelers will host free agent NT Cam Thomas on Friday.
Thomas has never lacked talent, but his consistency has been a huge issue in the pros, and he was benched late last season for Sean Lissemore. If you've never head of Lissemore, we don't blame you. Thomas is 27 years old.
Bills re-signed TE Scott Chandler to a two-year contract.
Chandler drew no known interest elsewhere. Turning 29 over the summer, Chandler is coming off a "career-year" that saw him post 653 yards and two touchdowns. With an erratic E.J. Manuel at the helm and Chandler possessing next to no movement skills, he'll be lucky to finish 2014 as a TE2.
Cardinals agreed to terms with WR/KR Ted Ginn, formerly of the Panthers, on a three-year contract.
Coming off a career year, Ginn will be a deep-ball specialist for vertically-obsessed coach Bruce Arians, and serve as a return man. Shutdown CB Patrick Peterson was surprisingly ineffective on punt returns in 2013, and doesn't return kicks. Ginn could do both in the desert. With Larry Fitzgerald and Michael Floyd ahead of him on the depth chart, Ginn won't be any sort of a fantasy consideration, but will get ample opportunity to be a play-maker.
Bears re-signed TE Dante Rosario.
Rosario was originally signed two weeks ago, then released on Monday. Presumably, the run blocker will now remain on the roster through the rest of the offseason program.
Lions signed DE/LB Darryl Tapp, formerly of the Redskins.
Tapp, 29, is a special teamer and reserve edge player. He does not figure to push for significant defensive playing time barring multiple injuries.
Colts signed C/G Phil Costa, formerly of the Cowboys.
Costa, 27 in July, appeared to be an ascending player in Dallas before falling out of the coaching staff's favor in 2013 as the Cowboys used a first-round pick on Travis Frederick. We wouldn't rule out Costa starting at center for the Colts, or at least giving Khaled Holmes a serious run for his money.
