Yeah, we do disagree....a bit. We would all would like to have 2 top end CB's, but we don't. However given the rest of the defense around them, I strongly believe they are GOOD ENOUGH to make this a top 10 defense....if not better. They both have played OK, and will likely get better as the season goes on, since this is both their first year starting.
However what I don't believe is that we can count on them to stay healthy for 12 more games. Bringing in McCourty ends this fear at worst, and improves the play at CB at best.
I'm in the group that believes that injuries and the refs are the only thing that can stop this juggernaut from getting another ring. Injuries are going to happen. Right now CB is vulnerable, very vulnerable
