In a recent mock draft conducted by ESPN analyst Matt Miller, the San Francisco 49ers prioritize reinforcing their offensive line and secondary with a series of strategic selections. Miller's projections, shared on social media, have sparked discussions among fans and experts alike.

With their first-round pick at No. 31, Miller suggests the 49ers select former Georgia offensive tackle Amarius Mims to bolster their offensive line. Known for his athleticism and toughness, Mims could provide immediate impact and support the aging Trent Williams.

In the second round, Miller proposes former West Virginia center Zach Frazier as a valuable addition to the 49ers' offensive line. Describing Frazier as a plug-and-play option with agility and toughness, Miller sees him as a potential first-round consideration if other offensive line options are unavailable.

Addressing the team's secondary needs, Miller's mock draft sees former Kentucky cornerback Andru Phillips falling to the third round, where he becomes a hopeful addition to fortify the 49ers' defensive backfield. Miller also includes the selection of another cornerback in the seventh round and a safety in the sixth round.

In addition to the offensive line and secondary, Miller identifies other areas of need for the 49ers. He suggests former Rice wide receiver Luke McCaffrey as a fourth-round pick, aiming to add depth and potential playmaking abilities alongside Christian McCaffrey. Miller also targets pass-rushing help in the fourth round with former Kansas edge rusher Austin Booker, known for his prolific sack numbers in college.

To strengthen their tight end position, Miller selects former Arizona tight end Tanner McLachlan in the fourth round. McLachlan demonstrated his skills at Southern Utah before transferring to Arizona and could provide an additional option alongside the All-Pro George Kittle.

The rest of Miller's mock draft includes several other selections, such as Mississippi State defensive tackle Jaden Crumedy in the fifth round, Wake Forest safety Malik Mustapha in the sixth round, and Marshall running back Rasheen Ali in the sixth round. The 49ers conclude with the selection of cornerback Ryan Watts from Texas in the seventh round.

Miller's mock draft selections aim to address the San Francisco 49ers' needs, targeting key positions on both offense and defense. As the NFL Draft approaches, fans and experts eagerly await to see how closely Miller's projections align with the 49ers' actual draft choices.
