It helps if you post the article or give other readers a chance to view the article rather than just posting your fairly dull opinion on it.
I'm sure if you were to read it properly, and factor in the aging players on the D it might make it a tad clearer.
Edit:
Rather than being accused of derailing a football topic thread, if anyone is interested then check out the article on NFL.com - it's actually about the Raiders and Reggie McKenzie making their Roster older at 27.- something years, but it is interesting non the less.
