Poll results: CB biggest concern

There is no mystery here.

The San Francisco 49ers should be more worried about the cornerback position than any other spot on the field. In our poll this week, we asked readers to vote on the biggest position of worry for the 49ers. Cornerback received an overwhelming 82 percent of the vote as of 8:55 a.m. ET Thursday. Backup quarterback received 10 percent, while inside linebacker and center each received just four percent of the vote.

The lopsided vote is not a shock. Cornerback is an important position and there is a lot of change there for the 49ers.

Truly, I don't think it's much of a worry. Tramaine Brock was terrific last year. A healthy Chris Culliver, first-round pick Jimmie Ward and rotational player Chris Cook should be able to overcome the offseason departures of Carlos Rogers (cut) and Tarell Brown (left in free agency).

But with a roster that has few worry spots, I can see the June concern at cornerback because of the offseason flux.
