Is Jeremy Langford ready to replace Matt Forte?

Here is the latest installment of the Chicago Bears' weekly mailbag. Thank you to everyone who submitted questions. Have a great rest of the week.

Jeff Dickerson: Let's slow down with Jeremy Langford. Matt Forte leads the NFL in yards from scrimmage (12,718) since 2008, and is second in Bears career rushing yards (8,602), fourth in rushing touchdowns (45) and third in total touchdowns (64). Forte is special. Langford is intriguing, but he's not on Forte's level. At least, not yet. Forte anchored Chicago's backfield for eight consecutive seasons. Some years Forte touched the ball more than 350 times. Langford had 170 touches in 2015. That number is bound to increase in 2016. Can Langford stay healthy? Can he be as productive when opponents spend the week preparing to stop him? I like Langford, but he only started two games last season. There is a lot we still don't know. So while Langford is the front-runner to be the No. 1 guy, I do expect competition at running back between Langford, Jordan Howard, Ka'Deem Carey and Jacquizz Rodgers, who impressed the Bears before he went on injured reserve last season.

JD: Alshon Jeffery is 26 years old. Kevin White turns 24 in June. Instead of allowing Jeffery to simply walk away next offseason, the Bears should attempt to keep them together beyond 2016. For all the injury concerns, Jeffery has the ninth most receiving yards (3,361) in the NFL since 2013. Jeffery's 12 games with 100-plus receiving yards are tied for fifth in franchise history, behind Harlon Hill (19), Johnny Morris (15), Brandon Marshall (15) and Mike Ditka (14). Jeffery is already 10th in team history with 252 receptions after playing just four seasons. So, I'm puzzled that some Bears fans want to kick him to the curb. Jeffery can play. But I do understand the complexities of contract negotiations. The Jeffery deal is not a simple one. He could very well play under the franchise tag in 2016; then try his luck in free agency next year. But even if White develops into a special player, the Bears won't be better off without Jeffery. This franchise hasn't won a Super Bowl in 30 years. They're not good enough to let young, talented players leave for nothing in return.

JD: Good question, Dan. John Fox is here for a minimum of three-to-four years. My guess is he sticks around longer than that. The Bears paid Fox a lot of money, and that contract is guaranteed. He is secure. Vic Fangio is a respected defensive coordinator. He is safe. However, Fox's long-term commitment to offensive coordinator Dowell Loggains is unknown. Loggains is much younger than Fox and Fangio, and therefore does not have that proven track record of success. There might be less patience with Loggains, who did call plays in Tennessee for 1.5 years. But big picture -- the Bears have no interest in making another round of sweeping changes. That would be expensive, especially with this coaching staff.

JD: Deon Bush has only been in the building for a couple of weeks. Coaches usually hold off on reaching any firm conclusions about players until training camp/preseason, when the team is in full pads. But the Bears thought enough of Bush to release Antrel Rolle after the draft. Bush should challenge for a starting job. My only quasi-critical observation (rookie minicamp is non-contact) is that Bush looked smaller than I expected. The only reason I bring that up is because he is known to be a big-hitter in the secondary. That caught me off-guard. But the Bears clearly like him.

JD: The problem with non-contact offseason workouts is that (barring a freak injury) a player really can't win a job on the offensive line. Offensive line coach Dave Magazu said the right side of the line is set with Kyle Long (right guard) and Bobby Massie (right tackle). Magazu additionally gave Charles Leno another vote of confidence at left tackle. That leaves left guard and center open. Cody Whitehair is a guard/center, but he figures to initially compete at left guard. The other guard/centers in the mix include Ted Larsen, Hroniss Grasu and Manny Ramirez. My best guess is that by the middle of the preseason, the Bears will have settled on their starting five.
