49ers enjoying depth at cornerback

The San Francisco 49ers' cornerback situation has been interesting. It's evolved since the offseason, and the group seems to be as strong as it has been all season as the team heads into the stretch run. The defense has played at a high level most of the year and has been dominant lately. The cornerbacks are big part of it.

Let’s look at the current core group:

Tramaine Brock: He’s been the best cornerback on the roster, answering every challenge as he has gone from a special-teamer to a nickel to a starter all because of injuries. He has started the past four games at right cornerback and been terrific. There’s a reason why the 49ers gave him a four-year contract extension.

Carlos Rogers: Rogers is still fine. He is a solid, crafty left corner who gives a full effort. He may be nearing the end, but he’s a big part of this team.

Tarell Brown: He may not regain his starting job. Brock took over when Brown hurt his ribs at New Orleans. Brown played Sunday on the left side in some formations. He will be a solid part of the defense the rest of the season.

Eric Wright: Any defense that has a player of Wright's quality in a reserve role is a good, deep defense. His presence completes a strong group.
