Woodson is still a playmaker, but declining in coverage, even since last year. Williams was a pro bowl CB last year who is playing nothing like a pro bowler this year (sound familiar?).
I think you make some good points about the rest of the defensive matchups, but disagree with these statements regarding the secondary:
T.Williams is not playing like a pro-bowler? Well, I actually agree to some level; but he is playing pretty darn good still. Look at his numbers from this yr through 14 games (he missed one game due to injury):
T.Williams 2011---4 INT's, 17 passes defended
(again, playing 2 games less than the 16 of last yr, as these stats are through 14 games played) that pretty much puts him right on the same level as his "pro-bowl" play of last yr
T.Williams 2010---6 INT's, 20 passes defended (with 2 extra games)
I am not seeing much difference. As far as Woodson goes, you may say his skills are not as good etc, but you have to respect his stats and playmaking ability from this yr. His numbers are just as strong as any year he's had in his career: (thru 15 games)
7 INT's and 16 passes defended
Even their #3 CB Sam Shields, still has 4 turnovers with 11 passes defended. That's way better production than even our #1 CB in McCourty...
This debate hardly matters anyway, unless both teams are there at the end. Then we'll have 2 wks to go back and forth.
