Simmons, KC's rookie left tackle, is expected to start and anchor the line after strong preseason showings. He is focused on technique and communication, with pass protection a key emphasis as he adjusts a mobile college game to the NFL's pace. His development under Heck, and his readiness for Week 1, are pivotal for KC's offensive stability.

Simmons, a rookie, has work to do to crack the roster; he’s on the radar for a Week 1 impact but must prove timing, alignment, and playmaking with Kingsley Suamataia and other rookies around him.

Simmons, a Chiefs rookie, lines up on the left side with Suamataia, forming the early interior duo KC is evaluating. His early preseason reps aim to prove chemistry with Suamataia while contributing to the left guard run and pass protection balance, potentially anchoring the early guard rotation.

Simmons drew early-round attention for his pass-blocking prowess at Ohio State (82.0 PFF grade) but sat with a season-ending knee injury. If he recovers and adapts to the NFL, he could stabilize KC’s blind side and unlock explosive potential from Mahomes.

Simmons’ pass-blocking work in limited snaps showcased credible rookie protection potential, keeping KC’s pocket clean in a rotation-heavy environment. His development could factor into KC’s long-term depth and pass-protection strategy.
