The San Francisco 49ers have several needs they are looking to upgrade through the draft, but one of the biggest is looking to find a cornerback that can start opposite of Tramaine Brock. Matt Barrows of the Sacramento Bee details the 49ers' situation:
The 49ers certainly have room to draft a cornerback if the opportunity presents itself. General manager Trent Baalke mostly has been content in looking for diamonds in the rough late in the draft. The earliest he’s taken a cornerback is the third round, where he found Chris Culliver in 2011. Free agency could be another spot for a potential starter. The 49ers, for instance, were interested in Sean Smith the last time he was a free agent in 2013 but eventually backed off.
San Francisco has the No. 7 overall pick in the draft, and that's their best bet at finding a true starting-caliber cornerback.
Florida State's Jalen Ramsey is the top rated defensive back, but it's unlikely that he'll be available when the 49ers pick. That means their most realistic target is Florida's Vernon Hargreaves III, who is also projected to be a top 10 pick and is projected to be a true shutdown corner at the NFL level.
