As the 2025 NFL season looms, all eyes are on the San Francisco 49ers’ training camp, where rookies are battling to prove their worth. Among them is Alfred Collins, the 6-foot-5, second-round defensive tackle drafted 43rd overall out of the University of Texas. Expectations were high for the towering run-stopper, but his slow start in camp has raised eyebrows. However, defensive coordinator Robert Saleh is quick to dismiss any panic, revealing a surprising truth behind Collins’ struggles that’s far from the typical rookie narrative.
A Rocky Start, But Not a Red Flag
Collins, a 23-year-old with an impressive college resume of 141 tackles and seven sacks, was expected to bolster the 49ers’ defensive line, particularly against the run. Yet, his transition to the NFL has been anything but seamless. Observers have noted that Collins appears a step behind, struggling to adapt to the speed and complexity of the professional game. While some might assume this is due to a lack of talent or effort, Saleh paints a different picture.
“He’s coming along,” Saleh told the media on Saturday, as reported by The Athletic. “He missed all of [offseason workouts], not to make excuses for the young man, but he did. It was with a [calf] injury, so it wasn’t like he was doing D-line drills. He was just trying to get up to speed.”
That’s right—the “shocking” truth isn’t a lack of skill or drive but a calf injury that sidelined Collins during critical offseason preparations. Without those foundational reps, he’s playing catch-up in a high-stakes environment. Saleh, however, remains unfazed, emphasizing Collins’ work ethic and physical gifts. “He’s behind the eight ball, but he’s working hard. Love the way he’s approaching every day, and he’ll catch up. He’s a big body with good feet. Those are things you can’t teach.”
A Run-Stopping Specialist with Big Potential
Collins’ college tape showcases a player tailor-made for stopping the run, a skill he himself takes pride in. After being drafted, he boldly declared to 49ers.com, “The run will be stopped… They’re getting a run stopper for sure. Just great pad level, elite hands, great feet, play recognition to know what block is coming to you and then just getting off of blocks, doing your job at a high level.”
This confidence aligns with the 49ers’ vision for him. Last season, San Francisco’s run defense ranked a middling 15th in the NFL, allowing 2,118 rushing yards. With Collins’ 6-foot-5 frame, quick feet, and knack for shedding blocks, the team sees him as a key piece in tightening up their front seven. His ability to clog lanes and disrupt running plays could elevate the 49ers’ defense, making them a tougher matchup for ground-heavy opponents.
Patience Is Key
Saleh’s comments suggest that Collins’ slow start is a temporary setback, not a sign of failure. Missing offseason workouts meant he couldn’t refine his technique or build chemistry with teammates, putting him at a disadvantage. Yet, Saleh’s optimism reflects a belief in Collins’ ability to close the gap. His size, athleticism, and relentless approach in camp are promising signs that he’s on the right track.
For 49ers fans, this revelation should quell concerns. Collins isn’t struggling because he lacks the tools or mindset—he’s simply overcoming a delayed start. As he continues to grind through training camp, expect him to gradually showcase the run-stopping prowess that made him a second-round pick.
Looking Ahead
With Week 1 of the 2025 NFL season approaching, the 49ers are banking on Collins to find his footing. His development is crucial for a team aiming to improve on last season’s run defense and make a deep playoff push. If Collins can translate his college production to the NFL, San Francisco’s defensive line could become a force to be reckoned with.
For now, Saleh and the 49ers are preaching patience, confident that their rookie giant will soon live up to his potential. The truth behind Collins’ slow start isn’t a cause for alarm—it’s a reminder that even the most promising talents need time to shine.
