The Bears have had an active start to free agency, adding players like QB Nick Foles, TE Jimmy Graham and OLB Robert Quinn. Depth pieces like CB Artie Burns and OLB Barkevious Mingo will factor into 2020, too, and even though they aren't headline-grabbers, they will have an impact on the Bears' 2020 draft plan.

Despite that activity, the Bears still have a lot of work to do. There are holes remaining in the secondary and along the offensive line, which will be an early focus in this updated seven-round mock draft.

The Bears haven't filled the void left by veteran Prince Amukamara's departure. Artie Burns is an unreliable player and Tre Roberson is a CFL longshot. Kevin Toliver II has some upside, but a prospect with Terrell's starting pedigree would be great value here at No. 43. He'd immediately be in the mix for a starting job in 2020.

Ryan Pace hasn't addressed the offensive line in free agency. Incumbent starter Rashaad Coward remains atop the depth chart at right guard and Alex Bars, who joined the Bears as an undrafted free agent last year, has upside.

Jackson started 14 games for Ohio State last season, earning third-team All-American honors. He's a plug-and-play starter for a Bears team that can't afford underwhelming interior offensive line play, especially if Nick Foles wins the starting job. He's a pocket passer who needs a clean pocket. Jackson would be a big upgrade.

Wide receiver isn't a glaring need for the Bears, but depth at the position is never a bad thing. With most of the promising tight ends off the board at this point in the draft, Chicago turns to Cephus, who profiles as a physical intermediate target who's a reliable contested-catch option. 

Carter started 11 games for the Crimson Tide in 2019 and is destined for a reserve role in the NFL. The Bears' depth chart features Eddie Jackson and Deon Bush as starters, and Carter, who's more of a coverage player than run defender, would be a quality backup with special teams upside.

Khalil Mack and Quinn will combine to form one of the best pass-rushing tandems in the NFL, and Mingo will provide solid depth. But the Bears need to add youth to the position, and Coleman fits the profile as a developmental prospect who can be groomed into an eventual rotational role after a couple of seasons on the bench. 

The Bears' decision to re-sign Danny Trevathan instead of Nick Kwiatkoski puts pressure on Pace to inject more youth into the depth chart. Martin finished the 2019 season as an honorable mention All-Big 10 defender with 66 tackles, one sack and two interceptions.

Players at this point in the draft are longshots to make the team, and Martin would be no exception. But Pace has to swing on a linebacker at some point before the draft concludes.

After signing 33-year-old Graham in free agency, the Bears have to grab a younger and more explosive option in this year's draft. Enter Sullivan, who after beginning his career at LSU as a wide receiver, has as much upside as a pass-catching tight end as any prospect in this year's draft. He'll slide to the later portion of Day 3 because of his inexperience, but his ceiling is exceptionally high.
