What about door No. 3 for the 49ers?

The San Francisco 49ers need an edge rusher, if not multiple edge rushers. Cassius Marsh did some decent work off the edge, and Ronald Blair was a really solid rotational option, but they need a big time playmaker. At the same time, they could use a clear No. 1 cornerback for the long-term, some safety competition would be nice, and adding a linebacker to replace Reuben Foster should be a priority.

The question is what of that they cover with the No. 2 overall pick. Ohio State edge rusher Nick Bosa and Kentucky edge rusher Josh Allen have been the top two picks in a lot of 2019 NFL mock drafts, but USA Today’s Nate Davis offered a different take altogether in his recent mock draft. He has the Arizona Cardinals selecting Alabama defensive tackle Quinnen Williams to beef up their interior. Then, rather than have the 49ers select Bosa, he has them going for secondary help, with LSU cornerback Greedy Williams.

San Francisco could go any number of directions for a defense that failed to make big plays — and part of the problem was a league-low two interceptions. The Niners also surrendered an NFC-worst 35 touchdown passes. It would appear getting a capable youngster opposite Richard Sherman, especially one who nicely added to the impressive corner lineage in Baton Rouge, would pass the common sense test.

Williams is a guy some have considered if Bosa is off the board, but if Bosa and Allen were both still on the board, how many people would be down with passing on both of them for another option? I know we have had some folks advocating for something other than edge rusher, but based on conventional wisdom, it seems like this would be a surprise.

How would you grade this kind of mock draft for the 49ers?
