According to Matt Barrows of the Sacramento Bee, 49ers defensive coordinator Vic Fangio is starting to see some separation between Nnamdi Asomugha and Tramaine Brock.
Fangio is starting to see separation at no. 3 CB between Asomugha & Brock. He wouldn't say who was leading but noted NA's strong game in KC.

No one knows if Asomugha will ever be the player he was with the Raiders. All that matters is that he plays better then he did in Philly.
