Bears QB Mike Glennon recovers after shaky preseason debut

BOURBONNAIS, Ill. -- Every day at Chicago Bears training camp is about the quarterbacks. There’s still not a full-blown quarterback controversy -- Mike Glennon remains No. 1 on the depth chart -- 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).

Here's a closer look at their day Saturday:

Mike Glennon

Wow moment: After a shaky preseason debut, Glennon started strong Saturday, completing every pass attempt in the Bears’ opening 11-on-11 period. Glennon’s best throw of the session was a perfectly lofted deep ball along the left sideline that hit Kendall Wright in stride. Glennon later moved around the pocket to avoid pressure, stepped up, and fired a strike to Kevin White over the middle in another full team period.

Whoa moment: Glennon had a bad period later on when he failed to complete a single pass in 11-on-11. Not every throw was Glennon’s fault -- White dropped a pass over the middle -- but he had three passes broken up and missed Tarik Cohen in the open field entirely.

Mitchell Trubisky

Wow moment: Saturday wasn’t Trubisky’s best day, but he connected with Titus Davis on a big gain late in 11-on-11. Most of the credit goes to Davis, who reached around Bears defensive back Rashaad Reynolds to make a spectacular catch. Still, that was one of Trubisky’s lone highlights of the afternoon.

Whoa moment: Again, Trubisky didn’t look all that sharp. He was intercepted by safety DeAndre Houston-Carson in the red zone late in practice. On that play, Trubisky and receiver Daniel Braverman were clearly not on the same page. Regardless of who was at fault, the botched sequence kind of summed up the day for Trubisky. He wasn’t terrible, by any means, but he didn’t make many big plays in any of the 11-on-11 periods.

Mark Sanchez

Wow moment: Sanchez played a role in the play of the day when he tossed a fade pass to undrafted rookie Tanner Gentry, who turned his body to find the football and make a terrific touchdown grab.

Whoa moment: Sanchez was also picked off by Houston-Carson in the red zone. Sanchez, who was rolling left at the time of the interception, definitely wants that throw back. He didn’t get much on that pass and appeared to short-arm it. Sanchez also barely avoided throwing an interception to linebacker Dan Skuta in the first drill of practice.
