What happened: Henne argued Mahomes can bring his back leg through while maintaining balance during throws. The former Kansas City backup used the criticism to defend the quarterback's training-camp mechanics.
Why it matters: Full-participation clearance gives Kansas City a key checkpoint toward Mahomes' Week 1 goal. His response to full-team work will shape the Chiefs' preparation for the 2026 season.
By the numbers: Mahomes tore the ACL and LCL in his left knee on Dec. 14, 2025, and received full camp clearance roughly seven months later. Kansas City finished 6-11 and missed the playoffs for the first time since 2014.
What to watch: Mahomes' workload and recovery between camp sessions are the next markers. His stated target remains Week 1.
