The Cleveland Browns have a lot to evaluate with their first team units because they have a new head coach and a couple of high draft choices expected to step into the starting defense, see Dawgs By Nature for more on those details, but the Green Bay Packers aren't looking for much from their first team units.
Most of the first team players should be done by the end of the first quarter. I can't imagine Aaron Rodgers playing for longer than a couple series. Just a good opportunity to shake off the rust. And there should be some healthy starters sitting out. It was reported that Charles Woodson and Tramon Williams were likely to be held out, and I wouldn't be surprised to see little (if anything) from Chad Clifton, Donald Driver, and Ryan Pickett.
It will be interesting to see how starters Jermichael Finley, Ryan Grant, Morgan Burnett, and Mike Neal look in their return from last season's injuries. But again, they might be held back a little depending on how they've looked in practice. Finley was dealing with a minor injury earlier this week, and he could be held out as a precaution.
There are a couple of starting battles to watch. Should Derek Sherrod or T.J. Lang start at left guard? How about Frank Zombo or Erik Walden at outside linebacker? Those are the only two starting battles I would consider open.
I'll be watching the entire game because this will be my only chance all season to get an extended look at many of the backups, and to see which rookies deserve a roster spot this season.
