Packers??? are you for real?...they start Amhad Carroll, who if was released, probably couldnt even get a job with another NFL team.
You forget the Packers signed Charles Woodson this off-season giving them Woodson and Harris, both of whom have shown the same ability as D Hall to cover an opposing team's top wideout. All the teams I mentioned, IMO have a pair of starting corners that are each
better than Jason Webster. In some cases, the difference isn't significant. And Terence Newman may not be a reincarnation of Deion Sanders, but he definitely has J-Web beat.
The Bears CBs are a product of their front 7
I don't think either Tillman or Vasher are as good as their press clippings, but again both players are better than Webster, and have shown the ability to play with the league's best.
And we know D Hall is a good example that you don't have to consistently be at the top of your game to be considered one of the top cornerbacks in the league.
And Urlacher is a very good linebacker. You could probably say that Mike Singletary was a "product of the system" if you wanted to considering that in the mid-80s he was playing behind arguably the best D-line in the past 20 years. What makes Urlacher a special player is his range and versatility. Not saying he would excel at other positions, but if you moved him to safety (his college position), he would probably be able to perform about on par with your typical NFL starter at that position, if not better. That "typical" starter being someone closer to Keion Carpenter's ability than someone like Brian Dawkins. He can play any LB position whether in the 3-4, 4-3, or 4-4, has great burst to the football, hits like a truck, can cover, can blitz, so he's in essence a complete LB. Not to mention he's never had the horses up front that Ray Lewis has had from time to time in Baltimore. It sounds like we're on the verge of another "Who's better? Lewis? Urlacher? or Brooking? argument" which IMO if you've actually seen Lewis and Urlacher play, then you wouldn't put Brooking in their class. He just can't do the same things that those two players can do.
