This is the 2nd time in a week I've seen this particular mixed metaphor on the BY. Bad juju, and not good for MOJO. Don't be casual with your idioms, people.
Review:
Dominoes fall: This means that a series of events is set into motion, one triggering the next, in unstoppable fashion. Typically is associated with something negative. Example - As soon as the stripper began to sing like a canary, the dominoes began to fall, and Pitino was doomed.
Pieces fall into place: This means that various individual events occur that, in the aggregate, result in an overarching effect. Typically is associated with something positive. Example - Immediately after the hiring of Dan Hurley a top notch staff was assembled, several high profile athletes committed, and other non-obvious pieces fell into place to assure the resurgence of Husky Nation.
