49ers training camp preview: Defensive back battles rage, but depth is solid

SANTA CLARA – A priority for the 49ers this offseason was to nail down a nickel back who can smother slot receivers and stick his nose in on run defense.

Overlooked in the process is recognizing how well Charvarius Ward and Deommodore Lenoir paired as last season’s starting cornerbacks. When it comes to the 49ers’ defense, so much attention is cast on Nick Bosa leading the front line and Fred Warner dominating at linebacker. The secondary, however, appears deeper now in what should be another championship-contending season.
