After every Green Bay Packers game, Railbird Central will provide you with a look back while we hand out our blue chip, red chips and cow chips for yesterday's performance.

The blue chip, amazing performances:

• Michael Montgomery -- The defensive end is playing the best ball of his entire career. And he's played well for a couple games running now. I'm not sure if it's indicative that he's finally (!) arrived, or that he's playing his brains out in a contract year. His production on Monday night was superb: six tackles, 1 1/2 sacks, two hurries and a tackle for a loss. If Montgomery can keep up this kind of performance, he'd be great to have next year.

• The Pro Bowl secondary --As is usually the case, it wasn't the secondary's fault that the Packers lost the game. Okay, maybe it was a little bit of Aaron Rouse's fault, but the two guys headed to the Pro Bowl did well. Charles Woodson continued what might be the best season of his career with another pick and his willingness to tackle ball carriers bigger than himself. Congratulations to Nick Collins for setting the Packers interception return yardage record in a single season with his tied for the NFC-leading sixth interception. He defended three other passes as well.
  

The red chip, solid performances:

• DeShawn Wynn -- Wynn didn't do anything spectacular, but he made the most of his limited opportunities in place of Brandon Jackson, and kudos to him for that. His biggest play was converting a fourth down run, getting a hard earned four yards to keep the chains moving when the Packers decided to use Wynn instead of the the usual battering ram in Ryan Grant. Wynn also added one reception for seven yards and was an effective blocker in pass protection.
  

• Brandon Chillar -- Like Wynn, Chillar didn't do anything exceptional, but he was active. He led the team in tackles with seven including one for a loss and a quarterback hurry. Perhaps most impressive was when Chillar allowed his receiver to catch a pass but was able to tackle him before the first down marker, which happened on more than one occassion.
  

The cow chip, crappy performances --

• Run Blocking -- The Packers averaged a measly 2.2 yards per carry. That's not going to cut it in the cold weather when it becomes harder to have an effective passing game. Gone are the days when Chad Clifton was effective.

• Special teams --Let's count the miscues: The Packers gave up a 70-yard kickoff return to Danieal Manninng. The unit failed to stay in their lanes up the gut of the field and Jarrett Bush was carried for at least 25 yards. Here's a hint, when you've already given up over 35 yards on a play, don't sacrifice a solid tackle for a weak attempt at a forced fumble. Mason Crosby not only kicked two unsucessful field goal attempts, he also booted one kickoff out of bounds. The Packers also gave up a 24-yard punt return to the always dangerous Devin Hester. And there was a holding penalty on a kick return too.
