Is it officially a Steelers collapse?

Is it officially a Steelers collapse? Coaching is the biggest issue. It was a complete mismatch yesterday. Even without their best defensive player, the Chiefs' were well orchestrated. Mahomes numbers against the Steelers are just ridiculous. The Steelers had a bad start once again. We will have many of the same offseason questions again this year. Is there a middle ground between the hatred and the praise for Tomlin? He's a good coach, but is he the right man still in Pittsburgh? Joe doubles down on his Reid as COY pick. Are the Ravens the only team in the AFC that can beat KC?
