Dangle a DE of Sherman's ability for trade and it would get easily as much play around here. And wanting Ramsey in a year before four DBs are scheduled to hit the market is hardly a sign of CB bias. That's just a case of talent fitting need.
As for the 2007 Giants, that was a complete defense by the time they hit the playoffs. Their whole thing was getting hot right at the end of the season and winning the four playoff games from behind with Eli playing great football. Yeah, they had a great DL, but key picks got them past both Dallas and Green Bay that year. It's one case of a team whose DL was stronger than its secondary, sure. That happens. But if they didn't play complete defense, there's no way they complete the playoff sweep against Romo, Rodgers, and Brady.
