The San Francisco 49ers have found themselves shuffling their secondary with some regularity in recent weeks. Injuries have been a major issue http://www.49ersauthorizedshops.com/authentic-george-kittle-jersey , with Richard Sherman, Jaquiski Tartt, and Adrian Colbert all missing time due to injuries. Additionally, ineffectiveness at times from Ahkello Witherspoon and Jimmie Ward have resulted in some changes.This past weekend, the 49ers rotated Greg Mabin into the cornerback position in the second half. He played 29 snaps, and defensive coordinator Robert Saleh said on Thursday that will continue this week. The coaching staff was pleased with his work in practice thus far and earned an opportunity in their eyes.The coaches were impressed with the whole picture Earl Mitchell jersey , with Saleh complimenting his physicality, competitive toughness, and communication skills. He thought it showed up in the game tape, and even though Mabin gave one up, Saleh it was well contested.One big problem the defense has had is the turnover in trying to figure out how fits where. Saleh is hoping one of the cornerbacks can, “grab hold of [the job] and have a stranglehold on it and not let it go.” He described it as being something for the entire defense where Authentic K'Waun Williams jersey , it’s a challenge, “to grab your job by the neck and choke it out.”When you have constant turnover on defense, it becomes difficult for the unit to gel. Each player always has their own assignment to handle, but there is a certain chemistry that is critical for a defense to gel into a cohesive dominant unit. Each player needs to step up when it come to the team’s tackling issues, but the overall defensive performance could very well come together once they can get a clear starting lineup and rotation sorted out. The 2018 NFL trade deadline is a week away, and it looks like it could be a busy one. The Oakland Raiders traded wide receiver Amari Cooper to the Dallas Cowboys for a first round pick on Monday Youth Joe Staley jersey , and now the New York Giants have traded cornerback Eli Apple to the New Orleans Saints. Adam Schefter is reporting the Saints are sending a 4th-round pick in 2019 and a 7th-round pick in 2020 to complete the deal.The Saints have been looking for cornerback help, with injuries and inconsistency hurting them the first seven weeks. New Orleans is 5-1 and sitting on top of the NFC South. The Rams are the team to beat in the NFC right now, but without much else really stepping up thus far, it makes sense for the Saints to get aggressive at a position of need.This could mean the Cardinals are holding out for a particularly high price for cornerback Patrick Peterson. He wants out, and is the best cornerback on the market. Even if the Cardinals weren’t holding out for a ridiculous price, it would still cost significantly more than what the Saints appear to have given up for a solid addition in Apple. The 49ers have a need at cornerback with Richard Sherman dealing with a calf injury 49ers Arik Armstead Jersey , and the rest of the group struggling with anything resembling consistency — well, consistently good, I suppose.John Lynch and Kyle Shanahan have some decisions to make between now and next Tuesday as they look to the present and the future. This is a team playing 2018 to evaluate young players for 2019 and figure out what they need to do to surround Jimmy Garoppolo on offense and DeForest Buckner on defense with more talent. On Monday, Shanahan was asked if the team would be looking for options as the trade deadline approaches. He explained the value of improving, but also considering long-term implications.The next week will give us a better handle on where things might be headed over the course of next offseason.
