Mykel Williams is entering his second NFL season with the kind of buzz that usually follows a player who has already announced himself. The 49ers defensive end hasn’t done that yet in the box-score sense, but the league is watching closely anyway, because the ingredients for a real leap are all there.
His rookie year never got a full runway. A torn ACL in Week 9 cut it short, but even before that injury, Williams had already forced his way into a starting job. San Francisco saw the same traits that made him a first-round pick: size, athleticism and the kind of versatility that lets a defense move him around and trust him in different spots.
The encouraging part for the 49ers is that the recovery has moved faster than expected. John Lynch said in the offseason that Williams should take part in training camp in some capacity, and reports from rookie minicamp showed him already going through mobility and resistance drills as he works back from knee surgery.
What Williams did as a rookie went beyond sacks and splash plays. He didn’t pile up eye-catching numbers, but he was doing the dirty work that changes drives - setting the edge, taking on blockers and helping squeeze the pocket so someone else could finish the job. That’s why so many around the league view him as one of the biggest X-factors on San Francisco’s defense.
His college résumé backs up the hype. In three seasons at Georgia, Williams put up 14 sacks, 21.5 tackles for loss and 67 total tackles. Kirby Smart regularly highlighted his versatility and physical style, and those traits have carried over to the NFL.
Now the setup around him looks better, too. The 49ers are trying to get a pass rush back on track after injuries hurt that unit last season.
With Nick Bosa expected back and veteran additions helping along the front, Williams should see more chances to win one-on-one. Some league observers think that young defensive line could end up being one of San Francisco’s biggest strengths in 2026.
That’s why the breakout talk feels real here. Second-year players often make their biggest jump after a full offseason in the system, and Williams has the profile of someone ready to take advantage. If the knee holds up and the pass-rush game keeps coming along, he has a clear path to becoming one of the NFL’s next defensive stars.

49ers Backfield Battle Behind McCaffrey Just Took A Troubling Turn
The 49ers used a third-round pick on rookie running back Kaelon Black in April, a move aimed at deepening the backfield behind Christian McCaffrey. On paper, it was the kind of insurance policy teams like to have in place, especially with McCaffrey carrying such a heavy load as the centerpiece of the offense.
But the addition also adds pressure to a room that already includes Jordan James, who did not record a carry in 2025. Both rookies arrived with strong college rsums, which gives San Francisco some comfort about the positions future, but it also leaves an unsettled pecking order behind McCaffrey and a lingering question about how the 49ers want to sort out the depth chart.

Robert Saleh Just Sent 49ers Fans A Strong Alfred Collins Message
Robert Salehs latest comments offered a familiar kind of reassurance for 49ers fans: the coach who helped bring Alfred Collins to San Francisco still believes the defensive tackle has the tools to become a difference-maker. Saleh, now leading the Titans, was part of the staff that drafted Collins during his second stint as the 49ers defensive coordinator, and his confidence in Collins work ethic carries extra weight after a rookie year that never really got on track.
Collins had to deal with a rocky first season, including a training-camp absence tied to a contract standoff, but the expectation now is that hell be in camp from the start and get a cleaner runway. San Francisco also added Osa Odighizuwa this offseason, a move that should help the interior rotation and ease some of the burden on Collins as he tries to turn promise into production. [Read more 🡒]
49ers Gave This Undrafted Receiver A Real Shot To Make Noise
Wesley Grimes landed in Santa Clara as more than just another undrafted flyer, which is saying something for a 49ers receiver room that always seems to have a few names fighting for one last opening. The former NC State wideout signed a three-year deal that includes $200,000 fully guaranteed, a small but meaningful sign that San Francisco is willing to give him a real look instead of treating him like a camp body.
Grimes brings the kind of athletic profile that can turn a training-camp rep into a conversation: a 4.35-second 40-yard dash and a 35-inch vertical leap. Just as important for a team built around timing, spacing and yards after the catch, his style lines up with what the 49ers want to do, which is why this is the sort of signing that can quietly become more interesting as summer unfolds.
