Thats a tough one.
I do know I never, ever, ever want to be without a true #1 CB again.
But god, the Moss years were just a thing of beauty (to say nothing of what if Brady had an elite wr too comeuppance)
I would love it if Brady had Johnson, Green, etc... but those guys aren't available, Jackson isn't anywhere near that conversation. Revis impacts every defensive snap and like Moss is a first Ballot Hall of famer, for me it is no question at all, I would take Revis every time.
