BOURBONNAIS, Ill. -- Every day at Chicago Bears training camp is about the quarterbacks. There is no quarterback controversy -- Mike Glennon is the clear-cut No. 1 -- but plenty of intrigue surrounds Glennon (still a relative unknown), Mark Sanchez (former high-profile starter) and Mitchell Trubisky (No. 2 overall pick of the 2017 NFL draft).

Heres a closer look at their day Wednesday:

Mike Glennon

Wow moment: Glennon is clearly on the same page with wide receiver Cameron Meredith, one of Glennons favorite targets on the practice field. Arguably Glennons best throw of the day happened in the opening 7-on-7 period when he rifled the ball to Meredith, who broke hard toward the right sideline approximately 15 to 20 yards downfield. Glennon put the ball on the money. Glennon later found Meredith over the middle in 11-on-11.

Whoa moment: Glennon and Meredith did have a misfire on a deep ball in a full-team period. Meredith had a step on a defender downfield on the left seam, but Glennon sailed the ball over his head. Glennons ability to hit on those big plays is important. Again, teams are going to stack the box to stop running back Jordan Howard -- second in the NFL in rushing yards in 2016 -- which will create opportunities for the Bears in the vertical passing game. Glennon has to keep defenses honest.

Mark Sanchez

Wow moment: Cant remember a wow moment from Sanchez on Wednesday. He spent most of practice with the third team as the Bears wanted Trubisky to get some extra work.

Whoa moment: Sanchez was intercepted in the end zone by rookie Eddie Jackson, who rotated over from safety to pick off the ball by the front-corner pylon. Jackson also intercepted Trubisky over the weekend.

Mitchell Trubisky

Wow moment: First of all, Trubisky spent most of the day working with the second-team offense. That development is noteworthy in itself, although Bears coach John Fox downplayed it after practice.

Dont read much into it, Fox said. Its just a matter of getting guys through different centers, different groups. Its something that we mentioned would happen at some point throughout the camp.

Trubisky has shown throughout camp that hes mobile. The rookie successfully climbed the pocket in one team period and found Daniel Braverman wide open over the middle. Trubisky also targeted Kevin White on a couple of plays. White had one of his best practices of camp, catching multiple passes from both Trubisky and Glennon.

Whoa moment: Trubisky overshot Deonte Thompson in 7-on-7. Thats a throw Trubisky probably wishes he had back because Thompson was all alone in the middle of the field.

The Bears' next practice is scheduled for 10:30 a.m. CT Thursday.
