The San Francisco 49ers are back on the practice field for OTAs, and early signs point to a deeper, faster, and more versatile roster heading into the 2026 season. In this episode, David Lombardi breaks down standout performances from the opening week of OTAs, including an extended look at rookie running back Kaelon Black and why his skill set could help preserve Christian McCaffrey throughout the season. We also examine Isaac Guerendo's injury setback, the continued evolution of the 49ers' defensive line, and the explosive upside of rookie edge rusher Romelo Height. Plus, updates on the team's Australia travel plans, roster logistics, Brandon Aiyuk's status, and what to watch as the 49ers continue building toward training camp.
