San Francisco 49ers Mock Draft Roundup 3.0

Campbell's relatively short arms (32 5/8 inches) and narrow frame (77 3/8-inch wingspan) may push him inside at the next level, but the 49ers are thrilled to see him available here to challenge for the open left guard spot. Like the Colts' Braden Smith and others, Campbell may eventually get the chance to prove himself outside to replace Trent Williams or Colton McKivitz.

The 49ers have been churning the roster quite a bit lately, and have a need at corner. Barron is CB2 (behind Travis Hunter) on most boards, and while I'm not as high on him as the majority, this is a pick that would make sense for both sides.

The 49ers start to rebuild and reinforce their roster with a pick in the trenches. Harmon is equally adept at defending the run and pass, and can be asked to fill a variety of roles along the interior. He would be great in the 49ers' heavy use of twists and stunts, and he gives San Francisco a young player to start replenishing its recently tenacious front.

The 49ers wanted to trade down in this scenario, but the two most likely reasons for doing so — Warren and Jeanty — were off the board and the phone lines were dead. So San Francisco goes with Harmon, a big, productive defender with versatility on the inside of the line. No college interior defensive lineman had more quarterback pressures than Harmon last season, per PFF. The 49ers also have had good luck over the years with Ducks defenders — Arik Armstead, DeForest Buckner and Deommodore Lenoir. It's worth noting that GM John Lynch was among five 49ers scouts on hand for Oregon's pro day earlier this week and that he had dinner with Ducks head coach Dan Lanning. "He's become a good friend and ally," Lynch said Wednesday. — Matt Barrows

The 49ers' defense has seen a lot of departures this offseason, including at cornerback. Barron is one of the most consistent players on tape among prospects in this year's class and he can take the ball away. He'll be able to match up against some of the talented slot receivers in the division.

A polar opposite of the Bears a pick earlier, the 49ers lost several key starters in a salary-cap purge and now need to reshuffle the roster. At just 20-years-old, Membou is still learning the subtleties of the game, but he's agile and powerful, projecting as an immediate upgrade at right tackle and a quality candidate to succeed Trent Williams (when necessary) as Brock Purdy's blindside protector.

The 49ers will look a lot different in 2025, but with another first-round receiver on board, they can still be dangerous in the NFC.

General manager John Lynch can go in a lot of different directions with this pick, as the 49ers' roster from their Super Bowl team in 2023 has been decimated. I like Barron a ton, and he fits what San Francisco wants to do defensively. He's physical, has elite ability and athleticism and is a true competitor. That's exactly what Lynch is going to want.

In case you missed it, the 49ers suddenly have a lot of needs. A snippet of the key losses over the past week: Charvarius Ward, Leonard Floyd, Dre Greenlaw, Talanoa Hufanga, Javon Hargrave and Deebo Samuel Sr. That's a bunch of talent walking out the door, and the Niners could really address any of those spots.

But San Francisco also is working to extend quarterback Brock Purdy, and building up the offensive line in front of him has to be a priority. Aaron Banks and Jaylon Moore signed elsewhere, and Trent Williams -- who has two years left on his deal -- will be 37 this coming season. Membou is my top-ranked tackle in the class, and I see him sliding in on the right side, where he started 30 games in college. He also could play guard at a high level early in his career, however, then transition to left tackle down the road.

The 49ers defensive line took a massive step back from its Super Bowl form last season. John Lynch isn't going to let that happen much longer. Pairing the freakiest athlete in the class with defensive line coach Kris Kocurek is a tremendous match.

The 49ers aren't just overhauling the defensive front. They're overhauling the entire roster.

That leaves the team with no shortage of options, but the rarity of Kenneth Grant's physical ability and size makes him a hard selection to turn down. The 49ers are a blank slate at defensive tackle, with Jordan Elliott, Kalia Davis, Evan Anderson, and Kevin Givens looming as the only ones under contract.
