I won't go so far as to say that Bill blew it with the CB signings.. I know he didn't, though I am weary of the Browner signing.
What I was disappointed over was the Pats not signing one of the DTs like Lamarr Houston, Arthur Jones, or Linval Joseph. Joseph, especially, since he could play either DT or NT in the Pats defense and the fact that he went relatively cheaply.
That being said, Alex Carrington is still out there. So is Kyle Williams. And Williams has been a Pats killer in the past. Having him next to Big Vince would be awesome. Pats Sims is another name who I wouldn't mind seeing..
