BOURBONNAIS, Ill. -- A daily review of the hot topics coming out of Chicago Bears training camp:

• Safety Adrian Wilson seems to be gaining a level of comfort in Chicago’s scheme, which in turn has resulted in the veteran playing somewhat faster. But don’t be fooled by Wilson’s seemingly average workout pace as some within the organization believe he’s “practicing like a veteran,” meaning he’s expending as little energy as possible just to make it through camp and into the preseason games. For Wilson, the exhibition games are where he’ll make his mark, and that’s when people within the organization expect the safety to go full bore. Considering he’s currently in a backup role, expect Wilson to receive significant snaps late into the games against mostly backups, and he’ll need to play well -- nearly dominate -- before the staff feels comfortable enough to put him into the mix for one of the starting jobs. The coaching staff hopes Wilson pans out because if he does, it gives the Bears an intimidating force on the back end they haven’t had in several years.

• The Bears pumped in the music as usual for the individual portions of practice, but when the team simulated some live situations, staffers piped in crowd noise through the public address system. The extra noise didn’t seem to affect execution on either side of the ball.

• Strangely, Brandon Marshall, Alshon Jeffery, and Matt Forte seemed to drop more passes in one day Thursday than they had throughout all of training camp. Jeffery and Forte each dropped two passes with the former making up for it by hauling in a long ball late in practice between two defenders. Chris Williams, a candidate to become the club’s primary punt returner and a backup receiver, muffed a punt and also dropped a pass.

• Despite Marshall's drop, he made perhaps the catch of the day in a goal-line drill. With Demontre Hurst draped all over him, Marshall made a spinning one-handed grab for a touchdown. Marshall receives points for difficulty on this one as he caught the touchdown with his left hand.

• Just before the start of practice, the Bears announced they signed offensive lineman Graham Pocic to a one-year contract and waived receiver Terrence Tolliver with an injury settlement. Pocic signed with the St. Louis Rams in 2013 as an undrafted free agent out of the University of Illinois.

• Non-participants at practice Thursday included safeties Craig Steltz (groin) and Chris Conte (shoulder) along with guards Kyle Long and Eben Britton (hamstring). Long has been cleared to return to practice, but won’t be back in pads until the club’s night workout Saturday at Soldier Field. Britton wasn’t on the field with teammates as he spent all of the practice rehabilitating inside with athletic trainers.

• Jermon Bushrod, Stephen Paea, Austen Lane, and Jordan Mills were the stars of one-on-one drills featuring offensive linemen against defensive linemen. Paea made the most impressive move of the day, using a swim move to blow past Roberto Garza in just one step.

• The Bears practice again Friday at 9 a.m. CST.
