The Steelers lost yesterday by themselves. The ticky tac hold and tge missed dropped ball didn't help but let's get real. However, when it was coaches challenge only. The run to the line with the auto play was fair. Take your challenge and risk losing it and a timeout or don't get a good look. Once upstairs starting getting involved you can throw all that out the window. If the play is close hold it for upstairs look which of course allows for coach intervention. Or drop upstairs sticking nose in.
