After watching their defense struggle mightily in 2013, the Bears went "all in" during the draft, acquiring a number of young, athletic players to energize the unit. Although the production didn't really improve (after ranking 30th in overall and scoring defense in 2013, Chicago finished 30th in overall defense and 31st in scoring defense in 2014), the Bears certainly discovered some building blocks for the future. Kyle Fuller has the potential to develop into a "lockdown" corner on the perimeter. He has a knack for coming up with takeaways and gradually improved in coverage throughout the season. With a full offseason of work to refine his technique, he should become Chicago's No. 1 corner in 2015. A move to a new scheme could help defensive tackles Ego Ferguson and Will Sutton -- who "flashed" as rotational players -- grow into solid starters in the near future. The team hit on linebacker Christian Jones as an undrafted free agent, but the jury is still out on the ability of safety Brock Vereen and running back Ka'Deem Carey to become key contributors.
