Chicago Bears at Arizona Cardinals: Windy City Gridiron previews the Bears

The Arizona Cardinals take on the Chicago Bears in their third preseason game, and we will be getting a healthy dose of Mitchell Trubisky versus Blaine Gabbert.

Lester A Wiltfong Jr. took the time to look at three of the biggest questions heading into the game for the Bears.

1. How much will we see of Mitchell Trubisky

He's still technically the #3QB according to head coach John Fox, so he may not get in til the second half. I'd expect Mike Glennon to play most of, if not all of the first half. Mark Sanchez will get a few series', then it will be Trubisky time.

2. Some players who can make moves up the depth chart.

If Trubisky does what he did on Thursday, on Saturday, how can Fox not elevate him to number 2?

Corner Kyle Fuller has had an up and down camp, but with Prince Amukamara hobbled with a hammy issue this week in practice, Fuller may get some more reps to shine.

The nickel battle between Cre'Von LeBlanc and Bryce Callahan is very competitive. Both have had solid starts to their careers, so Bears' fans are keeping an eye on those two.

3. Names to know for the second half?

Backup center Hroniss Grasu has had a good camp, and he played well in the preseason opener. He was slated to be the starting center last year before blowing out his knee. The Bears moved Cody Whitehair to that spot, and now he's firmly entrenched there.

UDFA wide out, Tanner Gentry, has been arguably the star or camp by catching everything thrown his way.

Inside linebacker John Timu has been around a couple years now, and he always seems to be around the ball in preseason.
