49ers' biggest need is cornerback after free agency

The San Francisco 49ers face a significant need for a cornerback after losing Charvarius Ward to the Colts. Pro Football Focus analysts highlight this position as a priority, despite concerns about the current roster's depth. While the defensive line also requires attention following the departures of key players, the cornerback position is seen as more pressing. The 49ers recently signed Tre Brown, but his performance has not been strong. To address this need, the 49ers may consider drafting a cornerback, with Michigan's Will Johnson suggested as a top candidate. However, selecting him could require using their first-round pick, complicating their draft strategy.
