49ers Post-Draft To-Do List: The Aiyuk Saga, O-Line Battles, and a Bosa Reunion?

Who's in at left guard?

With 10 of 11 starting spots on offense effectively settled, the lone vacancy sits at left guard. In 2025, the Niners leaned on a rotation that included Connor Colby, who remains the incumbent but faces stiff competition. To bolster the unit, San Francisco signed veterans Robert Jones and Brett Toth and used a draft pick on Washington's Carver Willis. While Willis played tackle in college, the Niners project him inside.

"He'll be in the competition," coach Kyle Shanahan said of the guard group. "When we get to OTAs, hopefully we have a number of guys fighting for that spot." If Jones can prove he has fully recovered from the neck injury that sidelined him for all of 2025, his 17 games of starting experience for the Dolphins might give him the early edge.

What about safety?

The 49ers used their eight draft picks to address the defensive front and wideout depth, but they notably bypassed the safety position despite several high profile prospects being available.

Currently, the 49ers are looking at a returning core of Ji'Ayir Brown, Malik Mustapha, and Marques Sigle. While this group showed flashes last season, Brown is entering a contract year and Mustapha is still developing. The team did add versatile defensive back Ephesians Prysock in the draft and signed Siran Neal in free agency, but a true veteran anchor at safety is missing.

"We’ve got a group that we really do like," Lynch said. "But kind of the way the board fell, it just didn't work out. The work's not over."

Will the 49ers finally sign Joey Bosa?

The "Bosa to the Bay" rumors have reached a fever pitch now that Joey Bosa is a free agent following a solid 2025 campaign with the Buffalo Bills (79.3 PFF grade).

The 49ers have cleared significant cap space by restructuring Osa Odighizuwa’s deal and extending Williams, fueling speculation that they are saving room for one last "all-in" move. While the team drafted Romello Height to assist Nick Bosa off the edge, Joey represents a level of pedigree no one else on the market can match.

"I'll never say never," Lynch said regarding the elder Bosa. "We'll never close the door to things like that." If Joey remains unsigned as June approaches, the prospect of the brothers finally wearing the same jersey becomes more of a possibility.
