While much of the focus of the Bears offseason has been on their need to fix their front seven, particularly their run defense, they'll also need to improve their cornerback play.
Charles Tillman is a free agent and will be 33 at the start of next season. He struggled with consistency and injuries in 2013, although he still showed a knack for taking the ball away.
While he made headlines last week saying he'll "retire a Bear", there's no guarantee he'll be back next season.
The Bears have Jennings on the other side and Isaiah Frey did a solid job as a nickel corner. Zackary Bowman—who filled in while Tillman was injured—did an admirable job, but had quite a few struggles against even decent receivers.
In a division with Calvin Johnson, Greg Jennings, Jordy Nelson, Randall Cobb and the rapidly-developing Cordarrelle Patterson, the Bears need to make sure they have guys who can cover.
Free Agency: Corey Graham
Lovie Smith never wanted to give Graham a shot on defense and he's proven that was a mistake in his two years in Baltimore.
Graham was a fifth-round pick by the Bears and was with them for the first five years of his career. He started in 2008, picking up 91 tackles, an interception and a forced fumble, but was replaced the next season.
While the Bears went through a number of players—including Bowman—opposite Tillman, Graham was never given another shot.
He broke the starting lineup early last season in Baltimore and has been a solid player ever since, playing both in the slot and out wide. Over the last two seasons, he's combined for 134 tackles, three forced fumbles and six interceptions, not counting the two he got on Peyton Manning in the 2012 playoffs.
Unlike some of the other free agent corners, Graham will likely come at a reasonable price. The Bears are already paying Jennings top dollar, so it's unlikely they'll want to put a lot more money in the position with so many needs elsewhere.
NFL Draft: Justin Gilbert
If Gilbert is available, don't be surprised if the Bears pull the trigger.
Some project Gilbert to go in the top 10, but others aren't as high on him. It's entirely possible that he's available at 14 when the Bears pick and, if he's rated higher than anyone else they have on their board, he could be their guy.
Unlike adding a high-priced cornerback in free agency, Gilbert will be reasonably cheap with the rookie wage scale. He could develop as a shutdown corner opposite Jennings and then replace Jennings as the team's top cornerback when the time comes. Jennings is 30, the Bears have to be mindful of how long he can continue to play at a high level.
Gilbert is big and fast, a necessity in a division with "Megatron." Plus, it's well known how much general manager Phil Emery likes measurables.
Should the Bears choose to wait and draft a cornerback later, there are some good options like Stanley Jean-Baptiste of Nebraska and Pierre Desir of Lindenwood.
