Big splashes have happened elsewhere in NFL free agency; in New England it's been little ripples.On Thursday, the Patriots announced the re-signing of special teams ace Matthew Slater and the acquisition of former Bears defensive tackle Marcus Harrison. The 26-year-old Slater was a Pro Bowler in 2011 and has worked at safety and wide receiver in a pinch. He had a team-leading 17 special teams tackles in 2011. Harrison was taken in the third round out of Arkansas in 2008. He's 27. He spent a day with the Patriots last Octiver after being released by the Bears coming out of 2011 training camp. .AOLWebSuite .AOLPicturesFullSizeLinkheight: 1px; width: 1px; overflow: hidden;.AOLWebSuite a color:blue; text-decoration: underline; cursor: pointer .AOLWebSuite a.hsSig cursor: default
