Nnamdi Asomugha has secured the San Francisco 49ers' No. 3 cornerback job, overtaking Tramaine Brock.
"He's done well in his reps that he's had in the game and in practice," Fangio said, via the San Francisco Chronicle. "Particularly the last two or three weeks, he's played much better."
Asomugha has struggled as a slot corner, so it remains to be seen how the 49ers will work him into the defense in passing packages.
