Chicago's plan always has been for Trubisky to one day assume the starting role - he's the second overall pick of this year's draft - but the club's stated preference is for Glennon to be the guy in 2017. If he has to sit the entire season, was he worthy of the draft position?
What is a good bet is Trubisky taking snaps with the second team in that practice.
As for Trubisky, the kid played extremely well, immediately setting off social media chatter over letting him compete for the starting job.
He was a flawless 4 for 4 on that first-half 2-minute drill that culminated in his first NFL TD pass, to Victor Cruz, of course, for the Bears' first score of the night. In his lone quarter of play, Sloter completed five of six passes for 94 yards, including a 47-yard touchdown to rookie receiver Isaiah McKenzie. Pace gave the same message to Trubisky that evening: Glennon is the starter. I do not want to overreact to one preseason game against backup defensive players, but I can not help but be excited. Unlike Siemian, Lynch got slightly better as the night progressed, saving his best drive for last. That's how the preseason goes.More news: Cuban diplomats expelled from United States over mystery illness

"Each time I'm in there with my teammates just show command at the line of scrimmage, drive the ball down the field, be efficient, pick up first downs and hopefully finish in the end zone a couple times".
Sloter finished the game 5-6 for 94 passing yards, one touchdown and a ideal passer rating of 158.3.
It wasn't much better for Mark Sanchez, who was 1 for 4 passing and only 4 yards gained on 10 plays before Mitch Trubisky was brought in with 1:55 left in the first half for some 2-minute-drill experience.
But Trubisky's athleticism was evident as he moved out of the pocket. The stage didn't seem too big for him. Leonard Floyd, the first-round pick past year, flew off the left edge to sack Broncos quarterback Trevor Siemian, and Cohen was as elusive against an opponent as he has been against teammates in training camp.
"Ideally, right, you want to score every time, but getting the ball that deep on your first drive and moving it down the field and kicking a field goal, on the road especially - if you look at the grand scheme of things - that's probably a pretty good first drive of the game", Siemian said.
