It's no secret that the San Francisco 49ers need to improve both sides of the trenches in the 2025 NFL Draft.

AJ Schulte's latest two-round mock draft for A to Z Sports has them doing just that. 

In the mock, the 49ers take Ohio State defensive tackle Tyleik Williams with the 17th overall selection, a pick that has brought them a lot of success in the relatively recent past.

Schulte writes of Williams:

"Tyleik Williams is a tremendous run-defender with jaw-dropping power, IQ, pad level, and hands. Williams handling the dirty work for so long has been pivotal to the Buckeyes' defense becoming one of the best in the country and has freed up other players to feast in pass-rush situations. He can be a terrific one-technique very quickly at the next level."

Given the 49ers' struggles on the interior defensive line, especially in run defense, Williams is a pick that would make a ton of sense. Still only 21, he would bring valuable youth to one of the older teams in the NFL.

And, with the Niners' restructuring the contract of Javon Hargrave in a decision that may foreshadow him being released as a post-June 1 cut in the offseason, there's more reason to think that defensive tackle could be in play for San Francisco in the first round.

In the second round, Schulte has the Niners addressing the other side of the trenches and using the 48th overall pick on Oregon tackle Josh Conerly.

The 49ers would benefit from an upgrade at right tackle, with Colton McKivitz remaining at best an average starter. However, Conerly has played the vast majority of his snaps at left tackle.

But that should not preclude the 49ers from considering Conerly, especially after a season in which Trent Williams has missed the last three games with an ankle injury, raising doubts about his ability to play into his 40s.

Landing Conerly, who has allowed only one sack and four pressures for the Ducks this year as they have marched to a Big Ten title, the top seed in the College Football Playoff and a place in the Rose Bowl, for the price of a second-round pick would be an astute investment in a player who could be Williams' long-term successor.

They need more of this down the stretch.
