Packers at Denver: What to watch for

Posted by ESPN.com's Kevin Seifert
My colleague Bill Williamson over in the AFC West will be in attendance Friday night for the Green Bay Packers' big preseason game at Denver. Bill will keep you apprised of the goings-on, but in the absence of actual news here are a few things to keep your eyes on from a Packers perspective:

1. Brian Brohm, Matt Flynn and the great backup quarterback debate. We all know that starter Aaron Rodgers had thrown a total of 59 career passes. But the depth behind Rodgers is starting to draw some scrutiny. Brohm and Flynn are both rookies, and Brohm -- expected to be Rodgers' primary backup -- has been shaky this preseason. (And, let's be honest, Flynn has been playing against third-stringers.) The Packers are hoping to see something reassuring from Brohm, who has a 41.0 passer rating this summer. Otherwise, they'll have to determine whether Flynn can handle the job or whether they'll need to re-think their position on pursuing a veteran backup.

2. Kabeer Gbaja-Biamila. There is some hope that Gbaja-Biamila will make an appearance after missing the past two weeks of practice because of a knee injury. When healthy, Gbaja-Biamila is one of the NFC's better pass rushers. But he carries a hefty cap number ($7.7 million) and at least one local writer considers him a possible roster casualty. A decent showing either Friday night or next week against Tennessee should quiet that talk -- if he gets on the field.

3. Cohesion on the offensive line. Center Scott Wells (side) isn't expected to play, so the Packers again will have to patch things together on the line. Jason Spitz, who could wind up the starting left guard, will replace Wells. Rookie Josh Sitton will be at right guard and Daryn Colledge will start at left guard. It's hard to find chemistry with weekly changes to the lineup, but it would certainly help the rest of the Packers offense get some good work in if the line can operate smoothly.
