As a former OL Coach, you cannot honestly beleive that missing an future HOF, ALL Pro LT changes the entire dynamic of the protection. Guys turning the corner all day on the back up would chase Mahomes into other trouble. It was clear and obvious the impact of the entire back ups they went into the game with, now some of the backups have had been in the entire seasons, but the loss of Fisher was too much for them to overcome. I don't disregard the impact of maybe an unfocussed over confident chief group, but that who they have always been, so why would this game be different?
I will agree, that the lack of committment to the Run to start the game was troubleseome as well.
