Kansas City opens abroad with a reworked left side: Kingsley Suamataia at left guard and Josh Simmons at left tackle, flanked by Creed Humphrey, Trey Smith and Jawaan Taylor. Mahomes faces a fierce Chargers front, a reminder of last season’s 36 sacks and a Super Bowl six-pack. Simmons has impressed in preseason, giving Chiefs faith that protection will improve and unlock more downfield chances for the MVP.
