I agree with the logic of the OP, although I'm not sure why Allen was included? Do I need another coffee or something?
Heck, we went to a Super Bowl with guys like Arrington, Sergio Brown, and Josh Barrett starting games in our secondary, and even used Edelman at times at corner.
And we won it all in 2004 without Law and Poole for most of the season, playing guys like Gay and Troy Brown.
We'd be a better team with Revis at $12M, sure. But I'm not ready to waive the white flag because he's not here. We've won a lot of games without him, or anyone close to him.
