Chiefs offense have been awful for the past month or two, they had a great game against the Raiders but have you seen them outside of that? They've had problems of their own and struggling against Denver right now.
I think Roman has his issues for sure but I don't think you replace him, he can't control the abomination of the OL neither can he control the injuries that this team suffers from.
You are correct but I think what people are frustrated about is the lack of adjustments. Excuse my ignorance of play calling terms but why not use quicker throws like if you know our oline sucks. The steelers oline sucks too and Ben's arm strength is definitely gone but look how quick he was getting the ball out. Did we even sack him once? I'm just saying change something lol.
