The Cowboys are on a bye week Ibraheim Campbell Jersey , and apparently they have decided that this is the perfect time to adjust their personnel. First, Dallas made a surprisingly aggressive move by trading their 2019 first-rounder for two-time Pro Bowl wide receiver Amari Cooper. It was a bold decision that could pay dividends for this offense.It appears that the Cowboys may not be done looking for additions to its roster. Ian Rapoport is reporting that former Raiders safety and 2017 second-round pick Obi Melifonwu is visiting the Cowboys on Thursday.Melifonowu, the 56th pick of the 2017 draft, took advantage of his freakish combination of size, 4.4 speed, and jumping ability to improve his draft stock ahead of the draft. The former UConn Huskies defensive back Allen Hurns Color Rush Jersey , and former teammate of Cowboys cornerback Byron Jones, possesses rare traits that give him a lot of potential.Unfortunately, the physically gifted defensive back has had trouble staying healthy during his young career, battling injury after injury. The Raiders placed Melifonowu on injured-reserve back in August due to a lower body injury. Now, Oakland has waived him, and he went unclaimed. Our friends over at Silver and Black Pride wrote that this could mean that the once highly-coveted prospect is looking to play in 2018.If Melifonowu is healthy https://www.dallascowboysfanshop.com/Maliek-Collins-Jersey , this could be an intriguing option for the Cowboys. We know that there is not much depth at safety on this team, and it is no secret that Kris Richard loves big, physical DBs. Melifonowu, 6-foot-3 and 224-pounds, certainly fits that profile.It is a little ironic that this is yet another Raiders player that the Cowboys have had interest in, as our own RJ Ochoa pointed out that the two teams have already made three deals in the second Jon Gruden era. Will the former second-round selection be joining his former teammates Chris Jones Jersey , Byron Jones and Amari Cooper? We shall see.UPDATE: The Cowboys are also looking at another defensive back.Former Raiders second round DL Mario Edwards Jr claimed off waivers by Giants After three seasons of chances from the Raiders, Mario Edwards Jr’s chances in Oakland ran out. But his NFL chances have not. After being waived by the Raiders on Saturday, he was scooped up off waivers by the Giants. The former second round pick never played a full season with the Raiders over three seasons, including missing all but the final two games of the season in 2016. And when he did play, he wasn’t a difference maker.Despite running with the first team defensive line all offseason and training camp, Edwards’s days were numbered with the drafting of defensive linemen Maurice Hurst and PJ Hall. Though it may have been the sudden emergence of players like Fadol Brown and Shilique Calhoun that ultimately sealed Edwards’s fate.Even with the release of Edwards Terrance Williams Color Rush Jersey , the Raiders kept ten defensive linemen in their initial 53-man roster. With Edwards set to make $1.9 million this season, it wasn’t worth it to have him as part of that crowd.Former Raiders cornerback Antonio Hamilton was also claimed off waivers by the Giants. Hamilton went undrafted in 2016 and spent the past three seasons with the Raiders as a reserve cornerback and special teams player.Follow @LeviDamien
