The San Francisco 49ers have wrapped up the 2025 NFL Draft, leaving fans buzzing with mixed reactions about the team's choices. While some selections spark excitement, others raise eyebrows, leading to varying draft grades across the board.

In an instant evaluation—a task that really requires years—we turn to ESPN's draft guru Mel Kiper, who has bestowed a B grade upon the 49ers. Kiper appreciates the team's focus on bolstering their defense, praising first-round picks like Nick Martin, Upton Stout, and CJ West. However, he emphasizes that the true test of this draft will hinge on Mykel Williams, the standout defensive prospect.

Kiper pointed out the rollercoaster history of general manager John Lynch and head coach Kyle Shanahan when it comes to their first-round picks, underscoring how Williams' performance could significantly impact the long-term perception of this draft class. If Williams emerges as a formidable counterpart to Nick Bosa, the 49ers' strategy may pay off handsomely. But if he falls flat, it could spell trouble for the franchise.

The 49ers entered the draft with 11 picks, including extra selections in the later rounds. Their priorities were clear: defensive tackle, offensive tackle, guard, cornerback, and edge rusher. While they effectively addressed their defensive needs upfront, concerns linger about the delayed focus on their offensive line, which didn't see reinforcements until the seventh round.

Kiper expressed enthusiasm for the defensive talent the 49ers secured, dubbing Martin, Stout, and West as fun players who could impact the game, even if they don't start immediately. Yet, he noted a potential overreach on some picks, particularly regarding wideout Jordan Watkins and running back Jordan James, whom he felt were selected too early.

One intriguing late-round choice was quarterback Kurtis Rourke, whose decision-making and timing impressed Kiper. There’s potential here—Rourke might just find a spot on the roster.

Ultimately, the success of this draft might rest primarily on the shoulders of Mykel Williams. The 49ers struggled last season, ranking 28th in pressure rate, and finding ways to alleviate pressure on their defensive backs is crucial. With Williams’ explosive talent, the hope is that he transforms into a game-changer. Can the 49ers maximize his high potential on every snap? The stakes are high, and fans will be watching closely.

As this offseason unfolds, Kiper’s B grade offers a blend of optimism and caution for the 49ers, who are eager to rebound from a rough 2024 season. With bold moves in the draft, only time will reveal how these rookies shape the future of San Francisco football.
