Each week leading to the draft, we'll look at a collection of mock drafts from various sources and compile the list of the top prospects projected to head to the 49ers.
We surveyed 75 online mock drafts this week and tallied which prospects are the most popular choices for the San Francisco 49ers, who currently own the No. 2 overall pick in this month's draft. The mock drafts include big-name sites like ESPN and NFL.com to smaller independent sites.
Former Ohio State defensive end Nick Bosa, who is visiting with the 49ers on Wednesday and Thursday, remains as the overwhelming favorite to become the No. 2 overall pick on April 25. Over 77 percent of mock drafts now have Bosa headed to Santa Clara.
Trailing a distant second and third are former Alabama defensive lineman Quinnen Williams and former Kentucky linebacker Josh Allen.
