Wright | ESPN.com The Chicago Bears' front office grunted through one of the league's busiest offseason of signings to put the team in position to draft the best player available in May while also minimizing the burden of the potential first-round pick to carry the savior label. So while the workload won't lighten as the Bears prepare for the NFL draft and the April 22 start of the offseason program, they've unwittingly utilized a core motto of former NFL coach Dennis Green: Plan your work and work your plan. That has led to the Bears signing 30 players since the final week of December, a group that includes 17 returners, 10 unrestricted free agents and three street free agents to drastically improve -- at least on paper -- one of the NFL's worst defenses of 2013. "I think we'll slow down a tad," Bears general manager Phil Emery said on March 31. "But we have a lot of work to do. We have some positions we want to make more competitive. The draft's around the corner." Not to diminish the work to be done over the next few weeks, but Chicago's activity up to this point should make things easier moving forward. Headed into the offseason, the Bears needed to address a defensive line that played a major role in 2013 in the defense allowing 5.34 yards per rushing attempt (the league average was 4.10), and did so by signing Jared Allen, Lamarr Houston, Willie Young, and Israel Idonije, in addition to bringing back Jeremiah Ratliff and Nate Collins. The club also re-signed starting corners Tim Jennings and Charles Tillman, while adding to the safety position by acquiring M.D. Jennings, Danny McCray and Ryan Mundy. So is the defense better now than it was in 2013? "The obvious answer to that would be we're healthier [than in 2013] because nobody's hurt," Emery said. "Also, I think we've added some guys at key points in their career. Jared adds experience, production, leadership. Somebody like Lamarr and Willie add some youth, speed and [physicality]. Really excited about Jeremiah Ratliff this year. He's excited about playing. He wants to finish here. He added so much the last few weeks [of 2013] in terms of leadership; unbelievably mentally tough player. So yeah, I think the collective group, we've gotten stronger and we're headed in the right direction as far as we want to establish as a defensive football team." Given the financial commitments to Houston, Allen and Young -- all defensive ends -- it'll be interesting to see how defensive coordinator Mel Tucker finds ways to get them on the field at the same time. Allen is the bona fide starter at right end, and Houston will play on the left side. But it's likely the Bears will take advantage of Houston's versatility and kick him inside to defensive tackle on passing downs while playing Young opposite Allen at end. Even without the benefit of the upcoming draft, Chicago's defensive line appears to be a more dynamic group than it was in 2013. "It's up to our coaches to find ways to get them all on the field at the same time or at different times or different personnel groupings or groupings against personnel," Emery said. Depending on the direction the Bears take in May in the draft, that task could become more difficult for Tucker. Despite the Bears adding Jennings, McCray and Mundy in free agency, the club could stand to acquire another safety in the draft capable of competing for a starting job; especially with the possibility Chris Conte might miss time at camp after undergoing shoulder surgery. But the club might see more value in using its first-round pick on one of the talented interior defensive line prospects such as Pittsburgh's Aaron Donald or Florida State's Timmy Jernigan, as picking a safety at No. 14 might be a little too high for the team's tastes. Surely, the Bears will address safety in the first three rounds, in addition to adding depth at some point at corner and at linebacker. Emery declined to say whether the signing of Allen or all the work done to revamp the defensive line will change the club's draft plans -- only that "it's always been about getting the best players possible to continue to build our team towards winning championships. To do that, you have to have high-quality players and players that can make plays. We talked at the end of the season about having more playmakers on our team." The Bears certainly added some. In the process, they made the possibility of a defensive renaissance similar to what was experienced on the other side of the ball in 2013 a potentially easier undertaking. They've planned their work and are working their plan.
