5 storylines to watch during Saturday's Bills-Bears game

The Bears host the Buffalo Bills at noon Saturday at Soldier Field for their second exhibition game.

Rarely will you find a preseason game as loaded with storylines as this one.

In this game preview, we'll focus on the five most relevant questions the Bears need to address and hopefully answer.

But first, how about what to focus on from you?

Unless you're living on Mars, you know that Mitch Trubisky will be starting at quarterback for the Bills.

Clearly his tenure with the Bears was a failure, but this is not the time or the place to re-litigate it.

Bears fans must make a choice as to how you will welcome him back.

Trubisky is one of the classier kids to ever pass through Halas Hall. He remains much beloved and respected among his teammates, and while he is responsible for his failure here, he is nowhere near solely responsible. And he did captain a stunning run to the playoffs for his old team that no one saw coming, finished his second season at the Pro Bowl and provided a number of highlight reel moments over his four seasons in addition to his disappointments.

Will you take the high road when he takes the field and welcome him "home," or embarrass Bears fans by piling on with boos?

QUARTERBACK

Like it or not, Andy Dalton is your Game 1 starter for now. After taking just six snaps last Saturday vs. Miami, head coach Matt Nagy has indicated Saturday could be Dalton's main dress rehearsal.

This is Dalton's first chance to quiet the haters and the critics.

Nagy hasn't ruled anything out for the final exhibition next week against Tennessee, saying some starters may play, others won't. Regardless, Dalton will have to show more in terms of first downs and points on the board than he did in two series last week.

All we know for sure about the test is he won't see the Bills entire starting 'D' the whole time.

Justin Fields will come out next, but regardless of what he does, if Dalton doesn't pile up some points and yardage, the boo-birds will come out, and the debate over when Fields takes the starter's baton will burn hot.

OFFENSIVE TACKLE

Jason Peters will play, although how much is uncertain. How he fares will be crucial to what comes next at both tackle positions. You're looking for conditioning tips, quickness, athleticism, and if it's all still there, we know he can play.

Larry Borom missed 10 days with a concussion, but he will be back Saturday. He might be the Bears' Plan B at left and right tackle, so how he performs will be crucial.

CORNERBACKS

If practice reps are an indicator, Kindle Vildor may have a big lead in the race for Kyle Fuller's starting job, but we can't count out Desmond Trufant or Artie Burns yet, and the race for Buster Skrine's nickel spot is still wide open with Thomas Graham Jr., Tre Roberson and Duke Shelley also still all in the hunt.

There aren't enough roster spots for all six plus Jaylon Johnson to stick.

TIGHT ENDS

Regardless of whether it's game managers Dalton or Nick Foles, or rookie student Fields, the tight ends will be their security blanket. Cole Kmet and Jimmy Graham are all set, but does Jesse James grab J.P. Holtz's spot? Can Jesper Horsted or Scooter Harrington play? And how many do they keep?

EDGE RUSHERS

Khalil Mack and Robert Quinn have looked great in camp, but the battle behind them between Jeremiah Ataochu, Trevis Gipson, James Vaughters, Charles Snowden and Sam Kamara is pitched.

Knowing that Ataochu is a lock and Christian Jones can slide outside too, which of the other four will emerge for what may be just one spot?
