Week 3 is usually the "dress rehearsal" game, so expect to see most starters playing into the 2nd half of their games.
This is also the last week before roster cuts begin, so those guys on the bubble really need to step up.
Jake Locker vs. John Skelton on Thursday night will be one to watch. I think Skelton has the starting job pretty much locked up unless he somehow plays worse than Kolb has so far this preseason.
The Bears playing the Giants scares me. For the love of christ o-line, do not get Cutler hurt vs. that d-line.
